IMPACT CITESCORE FACTOR 4.5 4.146 SCOPUS an Open Access Journal by MDPI The Importance of Shape-Tailoring at Nano- and Micro-Levels in Catalytic and Photocatalytic Applications Guest Editors: Message from the Guest Editors Dr. Zsolt Pap Dear Colleagues, Department of Applied and Environmental Chemistry, These issues are usually related to our everyday life and the University of Szeged, 6720 sustainability of our home planet (energy sources, water, Hungary, Hungary air, medical issues). Nanotechnology is nowadays “The [email protected] Technology” that answers the above-mentioned Prof. Dr. Lucian Baia challenges. Nano- and micro-sized materials are those Faculty of Physics, Babeș-Bolyai which will provide the solution, keeping in mind that every University, M. Kogalniceanu 1, particle’s properties are defined by its shape or secondary 400084 Cluj-Napoca, Romania organization level, the so-called hierarchical structures. [email protected] The peculiarities of each crystal shape are defined by the unique structure of each exposed crystallographic facet, Prof. Dr. Monica Baia Faculty of Physics, Babeș-Bolyai which can be tuned accordingly. Therefore, the present University, M. Kogalniceanu 1, Special Issue will be focused on contributions in the field of 400084 Cluj-Napoca, Romania (photo)catalysis, with special attention paid to the [email protected] correlation between the catalytic and photocatalytic activity of a nano- or macro-sized material to the morphology, while taking into account the very complex network of dependencies based on the activity-structure- Deadline for manuscript submissions: morphology triangle. 20 November 2021 mdpi.com/si/58487 SpeciaIslsue.
