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.

埃默里大学化学系克雷格·希尔（Craig Hill）博士的工作得到了化学系的无机，生物无机和有机金属化学计划的支持。该项目涉及新的无机络合物和系统，这些复合物和系统使用最环保和经济期望的氧化剂（氧气/空气）和溶剂（水）催化转化。具体来说，该项目将开发三个主要主题。首先，多铁多氧化酸盐（POM）将用作有机氧化的非常活性催化剂，并在室温下使用氧气在空气中使用氧气氧化矿化。 其次，将设计在水中用氧催化氧化，以利用稳定的POM集合，以消耗氧化过程中产生的酸性/碱性侧产物。最后，将使用停止流量方法确定POM催化剂的基本电子转移反应。 该项目强调利用环境良性氧化剂，例如空气和氧化水来氧化有机材料，包括纸漂白。随着开发更具环境友好和选择性的催化过程，这项研究将为社会带来巨大的好处。研究活动将为研究生和博士后同事提供出色的培训和教育经验。
