Abstract: Catalyst has important and wide application in our lives. Some metal surfaces have great catalytic properties for valuable chemical reactions. However, catalytic reaction processes are complex and difficult to understand. We therefore use model systems under ultrahigh vacuum to investigate the catalyzed reactions. In this presentation, I report our study of methanol decomposition on metallic nanoclusters supported on Al2O3/NiAl(100). We utilized STM to characterize the morphology of the supported nanoclusters and RHEED to characterize the atomic structures. The decomposition of methanol was studied by TPD, IRAS and XPS. This talk will also introduce the surface probed techniques used and general ideas of these researches.
