Alessandro Trovarelli has been a professor of Industrial Chemistry at the University of Udine (Italy) since 2003. Before joining the University of Udine he was a visiting scientist at the University of Oregon and Colorado State University. He is the head of the Catalysis for Energy and Environment laboratory at the Polytechnic Department of the University of Udine. He has worked in the area of heterogeneous catalysis for over 30 years. His main scientific interest is in the preparation, characterization, and testing of heterogeneous catalysts with particular attention to materials containing rare earths. The major applications investigated are the elimination of noxious compounds from car exhaust (NOx, VOC, and soot), the production of hydrogen for fuel processors in fuel cell applications, and chemical reactions for energy applications. He is currently on the Editorial Board for Applied Catalysis B: Environmental and the Journal of Rare Earths. He is the 2015 Recipient of the Ford Motor Company University Research Program Award and the 2022 recipient of the Giacomo Levi Medal award of the Division of Industrial Chemistry of the Italian Chemical Society. He is the author/co-author of ca. 200 articles and 7 international patents and served as guest editor for several special issues and books dedicated to the applications of ceria-based compounds in catalysis.
