Alessandro Trovarelli is Professor of Industrial Chemistry at the University of Udine (Italy) from 2003.  Before joining University of Udine he was 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 25 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), production of hydrogen for fuel processor in fuel cell applications and chemical reactions for energy applications. He is currently on the Editorial Board for Applied Catalysis B: Environmental and Journal of Rare Earths. He is author/coauthor of more than 180 articles and 5 patents and served as guest editor for several special issues and books dedicated to the applications of ceria-based compounds in catalysis.
