Abstract:
Control and tunability of the catalytic oxidn. of CO by gold clusters deposited on MgO surfaces grown on molybdenum, Mo(100), to various thicknesses are explored through temp.-programmed reaction measurements on mass-selected 20-atom gold clusters and via first-principles d. functional theory calcns. Au20 was chosen because in the gas phase it is characterized as an extraordinarily stable tetrahedral-pyramidal structure. Dependencies of the catalytic activities and microscopic reaction mechanism...     »
