Atomically Dispersed Supported Metal Catalysts: Synthesis, Structural Characterization, and Catalyst Performance

Bruce Gates, UC Davis

Monday, April 8, 2019 · 3:30 p.m.–4:30 p.m.  PT

Catalysts consisting of isolated oxophilic metal atoms bonded to supports are well established in industry. Noble metals isolated on supports are now drawing intense interest—stimulated by atomic-resolution microscopy images revealing the metal atoms and spectroscopic determinations of the catalytic site structures. These catalysts have been made on oxides, zeolites, carbons, and metals. New catalysts with unique properties are being discovered rapidly. Researchers are gaining deep insights to advance the science and bolster discovery of new catalysts. Crucial to recent progress are results determined at synchrotrons, including XANES and EXAFS spectra and ambient-pressure X-ray absorption spectra. Catalysts for prospective applications are oxide-supported cationic metals for CO oxidation and C–H bond activation, and metal-supported zerovalent metals for C–H bond activation and hydrogenations. This field is stimulating not only catalysis science but also surface science, materials synthesis, and electron microscopy.

About Bruce Gates

Bruce Gates

Bruce Gates is a Distinguished Professor in the Department of Chemical Engineering, UC Davis, having joined in 1992. Prior to his appointment at UC Davis, he held a number of positions, having been a research engineer at Chevron and the H. Rodney Sharp Professor at the University of Delaware, where he was also a director (and co-founder) of the Center for Catalytic Science and Technology. He received his BSc Degree from UC Berkeley, PhD from University of Washington (both in Chemical Engineering), followed by a Fulbright postdoctoral appointment at Ludwig Maximilians University of Munich. His research interests are in catalysis and materials, emphasizing fundamental investigations, motivated by technologically important problems and close interactions with industry. He is a member of the U.S. National Academy of Engineering and has received awards from the ACS, AIChE, the North American Catalysis Society, and the European Federation of Catalysis Societies. He has served on a number of editorial boards and was a member of DOE BESAC and serves on the SSRL SAC and NSLS-II SAC. He is the author of two catalysis textbooks.
