Abstract:
Based on the results of single-pulse, pump-probe and isotope exchange TAP experiments, the present study attempted to characterize the nature and bchaviors of active oxygen species of the newly developed Au/Ti(OH)4* catalyst (I) and a conventional Au/TiO2 catalyst (II) in low-temperature CO oxidation. Different activity between the two catalysts originated mainly from the different mode of O2 adsorption. Oxygen adsorbs molecularly and strongly (irreversibly) on (I), while O2 adsorbs molecularly, but weakly and the slower O2 diffusion on the conventional catalyst (II).
