Catalysis on the Nanoscale
Our research is focussed on characterizing the catalytically active sites of nanostructured surfaces and exploring how these are influenced or can be manipulated by variations in composition, particle size, morphology and chemical environment (e.g., support, reaction conditions). These goals are pursued by theory and experiment on model systems, both planar and powder, whose surface structure/morphology, and chemical composition are well-defined. We are particularly interested in exploiting the unique electronic and chemical properties of ultra-small clusters (1-50 atoms) of metals and metal compounds (oxides, sulfides) as novel catalytic materials. Cluster-based nanocatalysts are prepared by mass-selected deposition of gas-phase clusters which provides control over size and chemical composition with atomic precision. The model nanocatalysts are tested for conversion reactions involving CO 2 and methane, with an emphasis on revealing the atomic structure at interfaces and the interfacial electronic properties that underlie observed catalytic activity.
