Konstantinos Triantafyllidis, is Professor at the Department of Chemistry, Aristotle University of Thessaloniki, Greece, with undergraduate and PhD studies at the Department of Chemistry, University of Ioannina, Greece, postgraduate training at SHELL-Laboratorium, Amsterdam, and post-doctoral work at Michigan State University, USA. His research interests focus on the development of new materials as catalysts or sorbents (microporous and mesoporous materials, metal oxide nanoparticles, carbon-based or silica-based nanostructured materials, hybrid organic-inorganic materials, polymer nanocomposites), heterogeneous catalysis, and biomass valorization by thermochemical and catalytic processes. He is co-author of 100 publications in international journals (2500 references, h-index 28) and 6 book chapters (Elsevier, Wiley, etc.), > 100 conference proceedings, and co-inventor of one US and International patent. He has presented > 40 lectures at national and international scientific conferences and has served as Guest Editor for international journals, i.e. Catalysis Today (Elsevier), ChemCatChem (Wiley), Frontiers, as well as co-editor of an Elsevier book, entitled “The role of catalysis for the sustainable production of bio-fuels and bio-chemicals”. He has participated in 35 research projects and networks as a coordinator or principal researcher, funded by EU and Greek Ministry of Education/Research, European Space Agency (ESA), industrial contracts, etc.
