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.

埃默里大学化学系 Craig Hill 博士的工作得到了化学系无机、生物无机和有机金属化学项目的支持。该项目涉及新的无机复合物和系统，使用最环保和经济上理想的氧化剂（氧气/空气）和溶剂（水）来催化转化。具体来说，该项目将发展三大主题。首先，多铁多金属氧酸盐（POM）将用作选择性有机氧化和在室温下使用空气中的氧气进行羧酸氧化矿化的高活性催化剂。 其次，水中氧气的催化氧化将被设计为利用稳定的 POM 整体，消耗氧化过程中产生的酸性/碱性副产物。最后，POM 催化剂的基本电子转移反应将使用停流方法确定。 该项目强调利用空气和含氧水等环境友好的氧化剂来氧化有机材料，包括纸张漂白。随着更加环境友好和选择性催化工艺的开发，该研究将为社会带来巨大利益。该研究活动将为研究生和博士后提供良好的培训和教育经验。
