Dr. Papadas is an Environmental Engineer and Assistant Professor at the Department of Public & Community Health, School of Public Health at the University of West Attica in Greece. His research revolves around the development and t characterization of nanostructured semiconductor materials for applications in photovoltaics and photocatalysis. A key element of his research is the development of semiconductor nano-dimensional materials which absorb electromagnetic radiation in ultraviolet and / or visible region spectrum and converts it into chemical energy with high yield and chemical stability, as well as low production costs. Specifically, his research activities focus on the development of innovative semiconductor inorganic nanomaterials which aim at the photochemical conversion of solar energy through photocatalytic water splitting and photo-induced degradation of organic pollutants and toxic heavy metals. For example, the photocatalytic water splitting to molecular hydrogen production is one of the most promising methods for the photochemical production of solar fuels. He has participated in several EU, national and regional projects like THALIS (2011-2015), ERC Starting Grant (2012-2015), IKY (2015-2016) and ERC Consolidator Grant (2016-2021) as a Researcher B’ and Postdoctoral researcher, with activities that are related to the objectives of this project (development of semiconductor materials for environmental remediation). His teaching experience includes theoretical and practical undergraduate and post-graduate courses of Environmental Technology and Material Science (Inorganic Chemistry, Nano-chemistry, Electron Microscopy). Dr. Papadas has published 46 scientific articles in referred international journals most of these in highly cited journals and more than 20 papers of these published in IF>8.5 journals, are related to the objectives of this project, including Chem. Mater., Nanoscale, Chem. Eur. J. and J. Mater. Chem. A. and delivered over 35 presentations in international conferences and meetings. Based on Google Scholar data on Oct. 2022, the total citation times of his paper are over 1750 with h-index of 22 and a total impact factor over 250 (Based on Google Scholar, Aug 2023).
