Sotiris E. Pratsinis is Professor of Process Engineering & Materials Science at ETH Zürich, Switzerland, focusing on aerosol particle dynamics and scalable flame synthesis of catalysts, gas sensors and biomaterials. By closely investigating the effect of combustion variables on oxide particle characteristics, he pioneered the development of TiO2-based catalysts exhibiting superior photodegradation of phenol and other organics, compared to industry standard (P25). This motivated the development of flame spray pyrolysis (FSP) for synthesis of films and particles, up to 5 kg h–1 in his labs, perhaps the world’s largest such facility at an academic institution. In fact, his FSP is explored worldwide in academic and industrial laboratories and recently (2017) has motivated launching multi-million Euro/dollar research programmes by the German Science Foundation in a dozen German universities and the US National Institutes of Health in Harvard University. Together with Prof Baiker, he developed highly efficient V2O5/TiO2 catalysts for selective catalytic reduction of NOx, sulfur-poisoning resistant Rh/Pt/BaCO3/Al2O3 for NOx storage-reduction and mixed oxides for alkane upgrading. Now he and his students explore strong metal-support interactions (SMSIs) such as Ag-driven synthesis of Ti-suboxides for photoreduction of cationics (Cr6+) and sub-nano clusters and even single Pd atoms on TiO2 for highly efficient solar-light NOx conversion to nitrates.
