The chemistry and physics of metal clusters are studied, especially as they relate to heterogeneous catalysis, synthesis of ceramic powders, and genesis of metal- semiconductor interfaces. Three areas are addressed. The catalytic activity of organotungsten complexes toward hydrogenation of carbon monoxide is studied as a function of support and promoter. Chemisorption of hydrogen and of carbon monoxide on very small (5-50 atoms) clusters of Group VIII metals is investigated as a function of cluster size and shape. The reactions of reactive organometallic complexes on clean surfaces of indium phosphide will be investigated as a route to low-defect interfaces for microelectronic applications. A variety of techniques are used including temperature-programmed reaction (TPR) and extended X-ray absorption fine structure (EXAFS). This research is relevant to the production of high-technology ceramics, the development of new catalytic processes, and the production of high-quality microelectronic devices. It is also pertinent to the more general problem of the production and application of very small organized clusters, sometimes called nanostructures.
