Main Group Transition Element Clusters as Precursors to Supported Alloy Thin Films. Preparation, Characterization and Catalytic Evaluation

这个协作奖是在材料化学和化学加工倡议下颁发的，并得到了化学和材料研究部门的支持。本论文的研究主题是以过渡金属簇前驱体为主要基团的负载型合金薄膜的合成、表征及催化性能评价。具体地说，将在各种载体上制备、表征和分解铁硼化物团簇。将对负载型合金进行表征和评价，以催化甲烷氧化制甲醛。已知对甲烷部分氧化有效的固体催化剂将用硼化铁膜促进并进行评价。一旦了解了硼化物膜的作用，将对制备进行修改，以优化催化剂的活性和对甲醛的选择性。前驱体结构、薄膜性质和催化活性的%%-%%相关性将对基础科学和应用催化产生影响。

This collaborative award is made under the Materials Chemistry and Chemical Processing Initiative and is supported by the Divisions of Chemistry and Materials Research. The theme of the research is the synthesis, characterization and catalytic evaluation of supported alloy thin films prepared from main group-transition metal cluster precursors. Specifically, iron boride clusters will be prepared, characterized and decomposed on a variety of supports. The supported alloys will be characterized and evaluated for catalytic oxidation of methane to formaldehyde. Solid catalysts known to be effective for the partial oxidation of methane will be promoted with iron boride films and evaluated. Once the role of the boride films is understood, the preparation will be modified to optimize the catalyst activity and selectivity to formaldehyde. %%% Correlation of precursor structure, thin film properties and catalytic activity will impact both basic science and applied catalysis.
