建议：CTS-9816469 PI：Bruce C.Gates研究所：加州大学戴维斯分校标题：新颖的负载式金属簇合物催化剂摘要该建议是墨西哥国立理工学院的Bruce Gates教授和Miguel Valenzuela教授，以及Autonoma Metropolitana大学的GeolFetter和Pedro Bosch，以及Autonoma San Luis Potosi大学的Brent Handy之间的新合作。本研究的主要目的是测试由金属羰基前驱体制备的负载型金属簇合物催化剂。预计Ir和Rh的小团簇将稳定在MoS_2、水滑石和Al、Mg混合氧化物等载体上。其结构将通过EXAFS、IR和13C核磁共振谱确定。物理化学性质将通过化学吸附、TPD和量热测量来确定。催化性能包括甲苯加氢和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.
