  • Microwave-Assisted Synthesis of Coordination and Organometallic Compounds
    17 Microwave-assisted Synthesis of Coordination and Organometallic Compounds Oxana V. Kharissova, Boris I. Kharisov and Ubaldo Ortiz Méndez Universidad Autónoma de Nuevo León, Monterrey, México 1. Introduction Microwave irradiation (MW) as a “non-conventional reaction condition” (Giguere, 1989) has been applied in various areas of chemistry and technology to produce or destroy diverse materials and chemical compounds, as well as to accelerate chemical processes. The advantages of its use are the following (Roussy & Pearce, 1995): 1. Rapid heating is frequently achieved, 2. Energy is accumulated within a material without surface limits, 3. Economy of energy due to the absence of a necessity to heat environment, 4. Electromagnetic heating does not produce pollution, 5. There is no a direct contact between the energy source and the material, 6. Suitability of heating and possibility to be automated. 7. Enhanced yields, substantial elimination of reaction solvents, and facilitation of purification relative to conventional synthesis techniques. 8. This method is appropriate for green chemistry and energy-saving processes. The substances or materials have different capacity to be heated by microwave irradiation, which depends on the substance nature and its temperature. Generally, chemical reactions are accelerated in microwave fields, as well as those by ultrasonic treatment, although the nature of these two techniques is completely distinct. Microwave heating (MWH) is widely used to prepare various refractory inorganic compounds and materials

In carrying out this research, I complied with the rules of standard scientific practice as formulated in the statutes of Johannes Gutenberg-University Mainzto ensure standard scientific practice. Philipp Schäfer Abstract Metal-organic frameworks (MOFs) are crystalline, nanoporous materials that consist of metal cations and organic linker molecules with multiple functional moieties. The sheer infinite amount of possible metal ion-linker combinations makes MOFs in principle ready to be synthesized and tuned to desire for a large variety of applications as gas sensors, gas separation materials or as substrates for catalysis. Lack of synthesis predictability due to missing knowledge about the physicochemical processes during MOF production until now prevents their widespread industrial use. One specific synthetic pathway, namely the electrochemical synthesis, promises fast and versatile MOF synthesis. The electrochemical potential gives an easily controllable parameter that can be exploited to tune material properties such as the crystal size to desire.

  • Inorganic Chemistry Frontiers
    INORGANIC CHEMISTRY FRONTIERS View Article Online REVIEW View Journal | View Issue Low-temperature wet chemistry synthetic approaches towards ferrites† Cite this: Inorg. Chem. Front., 2020, 7, 3282 Stefano Diodati,a Richard I. Walton, b Simone Mascotto c and Silvia Gross *a Ferrites are a broad class of iron-containing oxides that includes spinel ferrites MFe2O4, perovskites MFeO3, and hexagonal ferrites (hexaferrites) such as BaFe12O19. These materials have a wide array of appli- cations owing to their diverse properties: notable instances include catalysis, piezoelectric components, magnetic components, biomedical applications, heterogeneous catalysis and photocatalysis. Given the growing importance of environmentally friendly, low-temperature methodologies to obtain functional materials, there is a growing interest in synthetic approaches which are compatible with the principles of “green chemistry”. In this context, wet chemistry represents an attractive choice, and furthermore offers the possibility of scale-up for manufacture of materials in volumes for practical application. Though there is a sizeable amount of literature on the synthesis of ferrites, the most common approaches require treat- ments at temperatures above 200 °C, either as the main synthetic procedure itself (thermal decompo- sition), or as a post-synthetic step (for example, calcination after sol–gel autocombustion). This review Received 9th March 2020, aims at summarising, categorising, classifying and critically discussing the different low-temperature Accepted 11th May 2020 (<200 °C), wet chemistry approaches employed in recent years for the synthesis of ferrites. This will DOI: 10.1039/d0qi00294a include hydrothermal, solvothermal, sonochemical, and microwave methods, with examples taken from rsc.li/frontiers-inorganic literature making reference to the various sub-classes of ferrites.

  • Synthetic Strategies in Chemistry
    SYNTHETIC STRATEGIES IN CHEMISTRY NATIONAL CENTRE FOR CATALYSIS RESEARCH INDIAN INSTITUTE OF TECHNOLOGY, MADRAS April 2008 PREFACE Synthesis has a central role in the development of Science especially in Chemistry. The strategies adopted in synthesis of molecules and materials have undergone considerable changes in recent times and it was felt that it may be necessary to assess and assimilate information on this topic in a single place. Though, no originality is claimed to the contents on this topic, the very fact that the available information on this topic is available in one place itself is considered to be a major step forward. To the best of our knowledge, such an attempt has not yet been made or available in literature, though various comprehensive assessment of various methods have been made and reported in literature. The contents of this ebook have been generated from the lectures delivered to the summer programme for the Children’s Club during April 14 to April 30, 2008 at the National Centre for Catalysis Research (NCCR). The members of the research community of NCCR are responsible for the compilation of information on each of the topics presented in this ebook. We have felt the need for a comprehensive compilation on this topic for various reasons and we do hope the scientific community will also feel the same way. It is possible that coverage may not be comprehensive. However, it is our first attempt to tread into an unknown territory in Science and make a compilation. In this sense this can be considered as our humble first attempt.

These properties are size-dependent and can be adjusted in the synthetic protocol modifying the reaction medium, time, source of heat, and the ligand used for stabilization. In the last decade, several spectroscopic methods have been developed for the analysis of organic and inorganic analytes in biological, drug, environmental, and food samples, in which different sensing schemes have been applied using ternary quantum dots. This review addresses the different synthetic approaches of ternary quantum dots, the sensing mechanisms Citation: Muñoz, R.; Santos, E.M.; involved in the analyte detection, and the predominant areas in which these nanomaterials are used.

  • Solvothermal Synthesis Routes to Substituted Cerium Dioxide Materials

Walton 1,* 1 Department of Chemistry, University of Warwick, Coventry CV4 7AL, UK; [email protected] 2 Johnson Matthey Technology Centre, Sonning Common, Reading RG4 9NH, UK; janet.fi[email protected] (J.M.F.); [email protected] (D.T.) * Correspondence: [email protected] Abstract: We review the solution-based synthesis routes to cerium oxide materials where one or more elements are included in place of a proportion of the cerium, i.e., substitution of cerium is performed. The focus is on the solvothermal method, where reagents are heated above the boiling point of the solvent to induce crystallisation directly from the solution. This yields unusual compositions with crystal morphology often on the nanoscale. Chemical elements from all parts of the periodic table are considered, from transition metals to main group elements and the rare earths, including isovalent and aliovalent cations, and surveyed using the literature published in the past ten years. We illustrate the versatility of this synthesis method to allow the formation of functional materials with applications in contemporary applications such as heterogeneous catalysis, electrodes for solid oxide fuel cells, photocatalysis, luminescence and biomedicine. We pick out emerging trends towards control of crystal habit by use of non-aqueous solvents and solution additives and identify challenges still remaining, including in detailed structural characterisation, the understanding of crystallisation mechanisms and the scale-up of synthesis.
