Novel Supported Metal Cluster Catalysts

提案：CTS-9816469 PI：布鲁斯C。盖茨研究所：加州大学戴维斯分校 标题：新型负载金属簇催化剂 摘要 该提案是布鲁斯盖茨教授（U.C.戴维斯）和墨西哥国家理工学院的米格尔·巴伦苏埃拉教授，以及自治大学的同事吉奥拉·费特和佩德罗·博世，以及自治大学圣刘易斯波托西的布伦特·汉迪。 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催化剂。预计Ir和Rh的小簇将稳定在诸如MoS 2、水滑石以及Al和Mg的混合氧化物的载体上。用EXAFS、IR和~（13）C NMR谱确定其结构。将通过化学吸附、TPD和量热测量确定物理化学性质。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.
