| Research Abstract |
The purpose of this research was to establish a method for measuring surface reaction rates as well as to establish a strategy for designing novel catalysts with high performances. Pulse molecular beam dosers and nitrogen Laser were installed in the Electron Stimulated Desorption system. TAP system was used to study a Ni catalyst prepared on silica support for reactions from biogas to syngas. For novel designed catalyst surfaces, immobilization of ionic liquid molecules on silica support surfaces and salt formation with chlorometallate anions were achieved. Shape control of nanocrystals of cobalt oxides and hydroxides were achieved. Density Functional Theory calculations were performed to obtain active structures of catalytic reactions and to clarify reaction mechanism for a Ru mononuclear complex attached on silica surface and Re cluster catalysts prepared in HZSM-5 framework.
