Research Abstract

We have developed a time-resolved x-ray absorption fine structure (XAFS) technique for dynamic catalysis research. This sophisticated technique allows us to investigate the structure kinetics/dynamics of catalysts under the working conditions. New catalysts for the direct phenol synthesis from benzene and the preferential CO oxidation under excess H2 were developed and their active structures were revealed. The real-time kinetics of a fuel cell Pt/C cathode catalyst in the voltage operation process was at first elucidated.
