Heterogeneous catalyst design is often hampered by a lack of information about the precise identity of the active sites. Synthesizing model catalysts with control of the local structure allows us to interrogate the active sites about their interactions with reactants, including activation and deactivation processes. The approach is particularly useful for dispersed metal oxides in which the active site consists of a single metal ion interacting with an oxide support. This talk will describe our efforts to make models of active sites for olefin polymerization and metathesis, to identify their structures, and to test their kinetic competence in catalytic transformations.
Prof. Susannah Scott obtained Ph.D. from the Iowa State University of Science and Technology. She is now the Duncan & Suzanne Mellichamp Academic Initiative Professor and Distinguished Professor of the University of California, Santa Barbara. And she is now the Chang Jiang International Professor of Dalian University of Technology. Her research interests focus on design of new heterogeneous catalysts for polymerization, metathesis and oxidation; applications of surface organometallic chemistry to active site characterization and thin film fabrication; inorganic reaction kinetics and mechanisms, especially related to the activation of small molecules; development and application of spectroscopic methods, particularly infrared and X-ray absorption; spectroscopies, to the study of interfacial reactions; Sustainable catalysis and routes to renewable energy, fuels and chemicals. Prof. Scott served as an associate editor for ACS Catalysis and the board of reviewing editors for Science.
