The application of surface sensitive techniques (XPS, UPS, LEED, HREELS, STM) to the study of surface chemical reactions of relevance to heterogeneous catalysis, including co-adsorption at metal surfaces. Recent projects include a study of the reactivity of the actinide elements thorium and uranium, which made use of a recently installed facility for inverse photoemission spectroscopy (IPES).
Metal oxidation and reactivity of oxygen states at metal surfaces. Many molecules, in particular hydrocarbons, may be activated at metal surfaces by pre-adsorbed or dynamically co-adsorbed oxygen species. The latter phenomenon is studied using gas mixtures, which often react differently to the individual components, which is clearly relevant to heterogeneous catalysis.
Preparation and reactivity of model supported metal catalysts. These analogues of high area powdered catalysts allow us to use surface science techniques to probe aspects of the mechanisms of heterogeneously catalysed reactions, such as particle size and support effects. A recent project investigated the mechanism of CO oxidation over Au/Fe2O3 planar model catalysts; this is a key test reaction for supported gold catalysts.
