报告人简介:

Dr Luwei Chen finished her bachelor and master degree education in Fujian Normal University and Xiamen University. She received her PhD from National University of Singapore (NUS) in 2000. She joined the Institute of Chemical and Engineering Sciences of Singapore (ICES) in 2003 and is currently a senior scientist and a team leader in the heterogeneous catalysis division. Her research interests include development of catalysts/materials for renewable/alternative energy; carbon dioxide capture and utilizations; mechanistic study of the gas adsorption as well as reactions on catalyst surfaces, using in situ techniques (XAS, XPS, UPS, Raman and FTIR etc.).

报告摘要:

Ethanol steam reforming (ESR, CH3CH2OH + 3H2O → 2CO2 + 6H2) is attractive for the production of renewable H2, which can be used for electricity generation in fuel cells. Elimination of side products such as CO and increment of H2 yield is crucial for the supply of H2 to fuel cells. In this study, the role of metal-support interaction among the three entities, i.e. Rh/Iriron oxide support at low temperature ESR was unraveled using a combination of in situ techniques, such as in situ XAS, XRD and DRIFT. This study demonstrates the importance of in situ techniques in detecting active phasesand understanding the reaction mechanism, which are crucialfor rational design and improvement of catalysts.
