Phosphorus is one of the most abundant elements on earth. My research group discovered in 2012 that elemental red phosphorus could be used for the generation of hydrogen from photocatalytic water splitting. Subsequent studies show that the activity of red-P can be greatly improved by structural modification. Among the phosphorus compounds, the most stable form is phosphate. Its photocatalytic property was reported decades ago. Phosphides have also attracted attention as they can replace platinum as an effective co-catalyst. In terms of environmental friendliness, carbon is even more attractive than phosphorus. In 2017, we found that carbohydrates in biomass can be converted to semi conductive hydrothermal carbonation carbon (HTCC). Under solar light illumination, HTCC generates photoexcited electrons, holes and hydroxyl radicals. These species can be used for photocatalytic treatment such as water disinfection and degradation of organic pollutants. We have prepared recently HTCC nanosheets from carbohydrates under hydrothermal conditions. The nanosheets are extremely active for photocatalytic disinfection compared to its bulk counterpart. As we can use agricultural waste as a raw material, our conversion of carbohydrates to HTCC may be considered as a “trash to treasure” approach.

Catalyst supports such as alumina, silica, titania, niobia, zirconia, zeolite, ceria, carbon-based materials, silicon carbide, metal-organic frameworks, and metal foams as used in various catalytic applications. The properties such as metal-support interaction, support size, morphology, acid-base nature, surface area, porosity of the support, and change in electronic properties of the metal clusters are crucial to the activity of the catalyst. Hydroxyapatite (CaP, Ca10(PO4)6(OH)2), is a double salt of tricalcium phosphate and calcium hydroxide- based material that contains both acid and base functionalities . Further, it exhibits high thermal stability, extremely low water solubility, and tunable surface area with or without porosity. The molar ratio of Ca/P in the stoichiometric form of CaP is 1.67. The ionic radius of CaP’s component elements (Ca and P) permits to certain extent the transfer or loss of ions within its crystal structure, consequently leading to non-stoichiometric CaP (Ca10-Z(HPO4)Z(PO4)6-Z(OH)2-Z ; 0 < Z ≤ 1) with a Ca/P molar ratio in the range of 1.50 ≤ 1.67 ≤ 1.80. This possibility helps in tuning the density of acid and base sites, which is not possible in the case of conventional catalyst carriers. Further, the calcium ions in HAP can be easily exchanged with most divalent cations, for example, Pb2+, Zn2+, Cd2+, Co2+, etc. without affecting the stability of the phosphate. These characteristics of CaP make it a unique support in heterogeneous catalysts. The functions and properties together with some applications will be discussed. Biography Ange Nzihou is Director RAPSODEE Research Center -CNRS, IMT Mines Albi – France. He is Editor-in-Chief of a Springer Journal “Waste and Biomass Valorization”. He has published more than 120 papers in peer reviewed journal and has been cited about 970 times. He is Guest Professor in number leading universities in USA, China and Europe. He has developed outstanding research in Thermochemical conversion Processes of Biomass and Waste to Energy and Added Value Materials. The second main field is the characterization, mechanisms, elaboration, functionalization of composite / hybrid materials (sorbents, catalysts, energy carriers, sensors) for energy and depollution. Catalysis and Chemical Engineering (CCE-2018) | Feb 19-21, 2018 | Paris, France 7 Characterization of Ce-Fe Oxides: Influence of the Dopant on the Structure Martin Schmal1*, Rodrigo Brackmann1, Fabio S. Toniolo1 and Sergio Gustavo Marchetti2 1NUCAT/COPPE/UFRJ, Brasil 2CINDECA-UNLP, Argentina Abstract +3 We studied the influence of Fe incorporation into CeO2 oxide on its physicochemical properties aiming application for NOx abatement by CO-SCR. Ce1-xFexO2-δ mixed oxides (x = 0; 0.05; 0.1; 0.15 and 0.2) were prepared by Pechini method.The + image of the mixed oxide Ce0,8Fe0,2O2-δ calcained and reduced of the mixed oxides. The EPR spectra revealed a presence of Ce 3 +3 in the non-doped CeO2, indicating the existence of intrinsic vacancies. In iron-doped samples are present isolated Fe sites + 3 with orthorhombic distortion, as well as Fe species in clusters. The Ce1-xFexO2-δ (x = 0,15 and 0,2) samples were investigated by Mossbauer before and after reduction. Results showed that there are 53% isolated Fe3+ and 47% of iron Fe3+clusters. The magnetization measurements and the presence of a pure Cerium have a diamagnetic component (typical of the CeO2 insulating structure) and a ferromagnetic component. This option is related to the oxygen vacancies through the structure Ce+3- δ - Ce+3, which characterizes a quasi-particle, where δ symbolizes an anion vacancy, which compromises the presence of this type of + 3 defeat in CeO2. All samples doped with Fe showed paramagnetic and ferromagnetic components. The doped component increases with the increasing Fe+3 content up to 10% and then decreases. This behavior is related to a competition between two mechanisms: a formation of polarized (Ce+3-δ-Ce+3 and Ce+3-δ-Fe+3) that increases ferromagnetism and the formation of super interactions exchange Fe+3-δ-Fe+3 anti- ferromagnetic.

Catalysis and Chemical Engineering (CCE-2018) | Feb 19-21, 2018 | Paris, France 8 Streamlined Nanocomposites for Heterogeneous Catalysis Hua Chun Zeng National University of Singapore, Singapore Abstract Systems of heterogeneous catalysis can be viewed as dispersed solid-liquid or solid-gas flows. Therefore, the geometric shape of particulate catalysts is fundamentally important, because an optimal shape configuration of catalysts can promote the transport processes and thus enhance catalytic activity in fluid-related reactions or environments. For example, a streamline body represents a superior geometry since it experiences minimum fluid resistance. However, utilization of streamline-shaped catalysts has remained an unexplored area due to the lack of easy-to-use techniques to produce such shaped catalysts, especially in the small length scale of submicron to micron regime. In this presentation, we will report our recent development of a class of prototype nanocatalysts with streamline shapes and complex chemical compositions. Advantages related to the streamline morphology of catalysts will be demonstrated with a number of solid-solution systems such as alcohol oxidation, olefin hydrogenation, and Suzuki-Miyaura coupling. Significantly, such streamline-shaped nanocatalysts indeed can reduce fluid resistance and provide structural benefits in catalytic applications compared to other commonly used counterparts. We envision that future development of streamline-based composite materials, in combination with various functional nanostructured materials, will play a greater role in design and synthesis of new generation catalysts or sorbents for multiphase processes.

Abstract Ammonia borane, NH3BH3, has attracted growing interest in recent years in the field of hydrogen storage due to its high gravimetric hydrogen content. In this study the reaction of NH3BH3 with various metal hydrides was investigated. The reactions with hydrides of lithium and sodium required a molar ratio of 1:2 in favour of NH3BH3 and + − the reaction products were characterised as [Li(NH3)] [BH3NH2BH3] and + − 11 23 [Na] [BH3NH2BH3] , respectively, through solid state B and Na MAS NMR and Raman spectroscopy. The reaction of CaH2 with NH3BH3 required a reaction stoichiometry of 1:4 and this reaction proceeded through a different reaction mechanism, forming Ca(BH4)2·2NH3. The crystal structures of Ca(BH4)2·2NH3 and Ca(BH4)2·NH3 were determined by powder diffraction methods and the reaction pathway investigated through solid state 11B MAS NMR spectroscopy.

  • Recent Developments on Hydrogen Release from Ammonia Borane
    6 Recent Developments on Hydrogen Release from Ammonia Borane Our group and others have been interested in chemical hydrogen storage materials that use the elements nitrogen and boron to chemically bind hydrogen. In these chemical hydrogen storage materials, hydrogen is ‘discharged’ by a chemical reaction and the hydrogen is ‘recharged’ by a chemical processing pathway. This makes them unique compared to metal hydride materials or carbon sorbent materials where the hydrogen release and uptake is controlled by temperature and pressure. One compound in particular, Dr. Abhi Karkamkar, Dr. Chris Aardahl, and Dr. Tom Autrey ammonia borane (AB = NH3BH3) has received significant Pacific Northwest National Laboratory interest given its stability and commercial availability. Ammonia borane, isoelectronic with ethane, is a solid at Introduction room temperature, stable in air and water and contains 190 g/kg (100–140 g/L) hydrogen. Figure 1 shows that if Record crude oil prices combined with public interest in energy a large portion of the hydrogen can be liberated, AB has a security have resulted in increased attention to a potential higher gravimetric density than most other reported chemical transportation economy based on hydrogen fuel. One of systems. This capacity coupled with stability has resulted in the greatest challenges is the discovery and development of renewed interest in studying ammonia borane as a hydrogen materials and compounds capable of storing enough hydrogen Ammonia Borane storage material. While the material would not be regenerated on-board to enable a 300-mile range without adding significant “on-board” it could potentially meet many DOE targets. Dehydrogenation Dehydrogenation of weight or volume to today’s conventional automobile.

  • High-Pressure Phase and Transition Phenomena in Ammonia Borane NH3BH3 from X-Ray Diffraction, Landau Theory, and Ab Initio Calculations
    High-pressure phase and transition phenomena in ammonia borane NH3BH3 from X-ray diffraction, Landau theory, and ab initio calculations Yaroslav Filinchuk,1* Andriy H. Nevidomskyy,2 Dmitry Chernyshov,1 and Vladimir Dmitriev1 1 Swiss-Norwegian Beam Lines, European Synchrotron Radiation Facility, 6 rue Jules Horowitz, BP-220, 38043 Grenoble, France, 2 Department of Physics and Astronomy, Rutgers University, 136 Frelinghuysen Road, Piscataway, NJ 08854, USA Abstract Structural evolution of a prospective hydrogen storage material, ammonia borane NH3BH3, has been studied at high pressures up to 12 GPa and at low temperatures by synchrotron powder diffraction. At 293 K and above 1.1 GPa a disordered I4mm structure reversibly transforms into a new ordered phase. Its Cmc21 structure was solved from the diffraction data, the positions of N and B atoms and the orientation of NH3 and BH3 groups were finally assigned with the help of density functional theory calculations. Group-theoretical analysis identifies a single two- component order parameter, combining ordering and atomic displacement mechanisms, which link an orientationally disordered parent phase I4mm with ordered distorted Cmc21, Pmn21 and P21 structures. We propose a generic phase diagram for NH3BH3, mapping three experimentally found and one predicted (P21) phases as a function of temperature and pressure, along with the evolution of the corresponding structural distortions. Ammonia borane belongs to the class of improper ferroelastics and we show that both temperature- and pressure-induced phase transitions can be driven to be of the second order. The role of N-H…H-B dihydrogen bonds and other intermolecular interactions in the stability of NH3BH3 polymorphs is examined.

  • Ammonia-Boron Trifluoride, NH3BF3, and ND3BF3
    Mem. Fac. Educ., Shimane Univ. (Nat. Sci.), Vol. 10. pp. 29 34. December 1976. An ESR Study of Radicals Produced in 7'-Irradiated Ammonia-Boron Trifluoride, NH3BF3, and ND3BF3 Kunihisa SOGABE* Abstract : ESR spectra of radicals produced in ammonia-boron trifluoride, NH3BF3, and ND8BF8 subjected to r-irradiated at 77 K were observed. From analyses of these spectra, the radicals were identified as a BF3-0r a NH8BF3-and a ･NHBF2. The latter radical is mterpreted to be prepared by a loss of a hydrogen from NH2BF2, which was produced by the decomposition of the NH3BF8･ ESR parameters of the ･NHBF2 radical were aF=26 G, aB=36G, aN=260 G, and aH=41 G, respectively. These results show that a dative bond of the NH3BF3 differs from that of the NH8BH3 in the bond strengh, although both bonds are stronger than a P-B dative bond in phoshine-boranes under ?'-irradiation Introductiom that a radical produced by T-irradiation of diborane, B2H6, at 77 K was not BH3 radical Boron halides or boranes in which boron formed by a symmetrical cleavage of a B-B atorn is short of two electrons having complete bond but a 'B2H5 by an extraction of one of valence shell could produce many interesting two bridged hydrogens.

Introduction Hydrogenation is one of the most important chemical transformations used in academia and industry and has received notable attention in the past century [1–7]. It can be performed via transition metal-catalyzed activation of molecular hydrogen and is used in large-scale applications such as hydrocracking [8,9] and the Haber-Bosch-Process [10] or in medium- to lab-scale applications for the synthesis of fine and special chemicals [1–3,11]. However, as the use of molecular hydrogen often requires harsh reaction conditions [12] and the regio- and stereo-selectivity are challenging to control [4,5,7,13], transfer hydrogenation has evolved as useful tool for specific and highly selective hydrogenation under mild conditions [3,4,7,12,14,15].

Abstract (Limit: 250 words) There are many remote traffic signals on the road that don’t have access to a regular power supply, so they use batteries that need to be changed quite often. A hydrogen fuel cell is an electrochemical device that combines hydrogen and oxygen to produce electricity. It offers a clean and high-efficiency energy source to circumvent the problems associated with the conventional batteries. However, one major drawback that limits its utility is the use of compressed metal cylinders as a source of hydrogen. Chemical-based hydrogen production can provide a very compact and low-pressure storage option for the controlled release of hydrogen gas in large amounts.

  • Ammonia Borane and Its Related Compounds
    SLAC-PUB-16095 High-pressure storage of hydrogen fuel: ammonia borane and its related compounds Yu Lin1,* , Wendy L Mao1,2 1Department of Geological and Environmental Sciences, Stanford University, Stanford, California 94305, USA 2Photon Science, SLAC National Accelerator Laboratory, Menlo Park, California 94025, USA E-mail: [email protected] Abstract As a promising candidate material for hydrogen storage, ammonia borane (NH3BH3) has attracted significant interest in recent years due to its remarkably high hydrogen content. Subjecting this material to high pressure not only enables the formation of novel phases and compounds with exotic properties, but also improves our basic understanding of materials behavior at different levels of atomic and molecular interactions. This review focuses on the perspective of high-pressure chemical hydrogen storage related to NH3BH3-based materials. Four main aspects are discussed: the structures and bonding of NH3BH3 over a wide pressure- temperature space, thermolysis of NH3BH3 at high pressure, the formation of a novel high- pressure H-rich compound as a result of storage of additional molecular H2 in NH3BH3, and the potential rehydrogenation of the thermally decomposed NH3BH3 under the extreme of pressure. This work is supported by the Department of Energy, Office of Basic Energy Sciences, Division of Materials Sciences and Engineering, under contract DE-AC02-76SF00515. 1. Introduction Hydrogen has been touted for its potential to be an environmentally clean and efficient energy carrier [1, 2]. Hydrogen has a high energy content per mass compared to gasoline (120 MJ/kg for hydrogen versus 46 MJ/kg for gasoline). However, hydrogen has a poor energy content per volume (0.01 MJ/L at standard temperature and pressure (STP) and 8 MJ/L for liquid hydrogen versus 34 MJ/L for gasoline).

    Diborane - Wikipedia, the free encyclopedia Page 1 of 5 Diborane From Wikipedia, the free encyclopedia Diborane is the chemical compound consisting of Diborane boron and hydrogen with the formula B2H6. It is a colorless gas at room temperature with a repulsively sweet odor. Diborane mixes well with air, easily forming explosive mixtures. Diborane will ignite spontaneously in moist air at room temperature. Synonyms include boroethane, boron hydride, and diboron hexahydride. Diborane is a key boron compound with a variety of applications. The compound is classified as "endothermic," meaning that its heat of formation, ΔH°f is positive (36 kJ/mol). Despite its thermodynamic instability, diborane is kinetically robust and exhibits an extensive chemistry, much of it entailing loss of hydrogen.

  • Ammonia Borane Composites for Solid State Hydrogen Storage and Calcium-Ammonia Solutions in Graphite
    Ammonia borane composites for solid state hydrogen storage and calcium-ammonia solutions in graphite Atahl Nathanson This thesis is in accordance with the requirements of the University College London for the degree of Engineering Doctorate February 2014 I Ammonia borane composites for solid state hydrogen storage and calcium-ammonia solutions in graphite Submitted for the degree of Doctor of Engineering February 2014 Abstract The dual problems of worlds growing population, increasing energy demand and global warming, necessitate an alternative to fossil fuels. Hydrogen is plentiful and has a high energy density but storage in high pressure tanks is complex and presents safety concerns. Ammonia borane (AB) is one of the most promising solid state hydrogen storage materials due to its high releasable hydrogen content (13.1 wt%), stability in air, and low toxicity. On heating, however, pure AB releases hydrogen only after long nucleation times and is accompanied by the liberation of gaseous impurities including borazine and ammonia; additionally, extensive material expansion and foaming occurs. AB composites with polyethylene oxide, polystyrene and imogolite have been synthesized. It is concluded that the decomposition of AB is best ameliorated by providing access to functional groups that catalyse alternative dehydrogenation routes. Lowering the onset of hydrogen loss to below the melting temperature limits the overall foam and expansion. The two dimensional confined motion of liquid ammonia in a multi staged ternary calcium ammonia graphite intercalation compound was studied with respect to temperature. Hopping diffusion at 300K gives way to rotation below 100K. The dynamics of this confined calcium ammonia solution are observed as similar to the three dimensional counterpart.
