Abstract
Recent experiments have shed light on how metal clusters behave as catalysts. Especially by studying bimetallic systems, electronic and ensemble (geometric) effects have been clarified. Strong metal support interactions (SMSI) may be explained due to “decoration effects”. It is apparent that morphology of the particles is extremely important in determining catalytic properties. Recent experiments in metal vapor chemistry for producing various catalytic morphologies are discussed, with special emphasis on the Pt°-Sn° system. Finally, new studies of gas phase metal cluster-hydrocarbon reactions are briefly reviewed with emphasis on Pt(n) and Nb(n).KeywordsBimetallic CatalystMossbauer SpectrumStrong Metal Support InteractionSmall Metal ParticlePlatinum ClusterThese keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
