Novel Supported Metal Cluster Catalysts

摘要该提案是Bruce Gates教授（加州大学戴维斯分校）和Miguel Valenzuela教授（墨西哥国立理工学院），以及大都会自治大学的Geolar Fetter和Pedro Bosch以及圣路易斯波托西自治大学的Brent Handy的新合作成果。本研究的主要目的是测试由金属羰基前体制备的负载型金属簇催化剂。预计Ir和Rh的小簇将稳定在诸如MoS2、水滑石和Al和Mg的混合氧化物等载体上。结构将用EXAFS， IR和13C NMR谱测定。物理化学性质将通过化学吸附、TPD和量热测量来确定。催化性能将涉及甲苯加氢和2,2,3,3，-四甲基丁烷氢解。

Proposal: CTS-9816469 PI: Bruce C. Gates Institution: University of California at Davis Title: Novel Supported Metal Cluster Catalysts ABSTRACT The proposal is a new collaboration between Prof. Bruce Gates (U.C. Davis) and Prof. Miguel Valenzuela, Instituto Politecnico Nacional, Mexico, and colleagues Geolar Fetter and Pedro Bosch, of Universidad Autonoma Metropolitana, and Brent Handy, of Universidad Autonoma San Luis Potosi. The main objective of the research is to test supported metal cluster catalysts prepared from metal carbonyl precursors. It is expected that small clusters of Ir and Rh will be stabilized on supports such as MoS2, hydrotalcites, and mixed oxides of Al and Mg. The structures will be determined with EXAFS, IR and 13C NMR spectroscopies. The physicochemical properties will be determined with chemisorption, TPD, and calorimetric measurements. The catalytic properties will involve toluene hydrogenation, and 2,2,3,3,-tetramethylbutane hydrogenolysis.
