Energy Conversion Processes with Perovskite-type Materials

Abstract

Mixed oxides derived from the perovskite structure by combination of A-and B-site elements and by partial substitution of oxygen provide an immense playground of physico-chemical properties. Here, we account for own research conducted at the Paul Scherrer Institute on perovskite-type oxides and oxynitrides used in electrochemical, photo(electro)chemical and catalytic processes aiming at facing energy relevant issues. Davide Ferri is currently group leader at thePaul Scherrer Institute and focuses research on catalysis and in situ/operando experiments using spectroscopy and diffraction methods. After studying industrial chemistry in Milano, he defended his doctoral degree at ETH Zurich in 2002 before making a short experience at Bruker Optics as sale manager and returning to ETH for a research assistant position. Before joining the Paul Scherrer Institute, he was group leader at Empa until 2012. Beside operando spectroscopy, he is interested in environmental catalysis, catalysis under unsteady-state conditions, the chemistry of perovskite-type oxides and catalysis in liquid phase. Emiliana Fabbri is a research scientist at the Paul Scherrer Institute. Her main research interests are on materials development for electrochemical energy conversion devices. This includes materials fabrication along with electrochemical and operando X-ray spectroscopy investigations of surface states and electronic structures of catalyst materials towards a fundamental understanding of reaction mechanisms as well as design principles for new materials.
