Oxometal Complexes and Redox Catalysis

埃默里大学化学系克雷格希尔博士的工作得到了化学系无机、生物无机和有机化学项目的支持。该项目涉及新的无机复合物和系统，这些复合物和系统使用最环保和经济上最理想的氧化剂（氧气/空气）和溶剂（水）催化转化。具体而言，该项目将制定三个主要专题。首先，多铁聚氧乙烯酸盐（POM）将被用作非常活泼的催化剂，用于在室温下使用空气中的氧气进行选择性有机氧化和羧酸的氧化矿化。 其次，将设计通过水中的氧的催化氧化以利用消耗氧化期间产生的酸性/碱性副产物的稳定POM系综。最后，POM催化剂的基本电子转移反应将使用停流法测定。 该项目强调利用对环境无害的氧化剂，如空气和含氧水来氧化有机材料，包括纸张漂白。随着环境友好和选择性催化工艺的发展，该研究将产生巨大的社会效益。该研究活动将为研究生和博士后提供优秀的培训和教育经验。

The work of Dr. Craig Hill, Department of Chemistry, Emory University is supported by the Inorganic, Bioinorganic and Organometallic Chemistry Program of the Division of Chemistry. The project involves new inorganic complexes and systems that catalyze transformations using the most environment friendly and economically desirable oxidants (oxygen/air) and solvent (water). Specifically, the project will develop three major topics. First, multi-iron polyoxometallates (POMs) will be employed as very reactive catalysts for selective organic oxidations and the oxidative mineralization of carboxylic acids using oxygen in air at room temperature. Secondly, catalytic oxidations by oxygen in water will be designed to utilize stable POM ensembles that consume acidic/basic side product produced during oxidations. Finally, the fundamental electron transfer reactions of the POM catalysts will be determined using stop-flow methods. The project emphasizes utilization of environmentally benign oxidants such as air and oxygenated water to oxidize organic materials, including paper bleaching. The research will lead to great benefits to society as more environment friendly and selective catalytic processes are developed. The research activity will provide excellent training and educational experiences to graduate students and post-doctoral associates.
