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 hydrogen peroxide) and solvent (water). Specifically, the work consists of a three-component program: (a) the first deals with developing "inorganic picket fence porphyrin" equivalents to uncover new oxygen binding and catalytic oxygenation chemistry; (b) the second concerns new multi-iron containing polyoxometallates with long-chain organic groups that exhibit surfactant-like properties permitting greater solubilization of organic substrates in oxidative catalysis; whereas (c) the third deals with catalytic oxidations by oxygen in water in which thermodynamically stable catalysts self-buffer under turnover conditions.Several new polyoxometallate systems will be fabricated which, if proven robust, represent an important class of low-cost oxidation catalysts for fine chemicals production. The project emphasizes utilization of environmentally benign oxidants such as air and oxygenated water to oxidize organic pollutants. 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/空气和过氧化氢）和溶剂（水）来催化转化。具体来说，这项工作由三个组成部分组成：（a）第一个涉及开发“无机栅栏卟啉”等同物，以发现新的氧结合和催化氧化化学； (b) 第二个涉及具有长链有机基团的新型多铁多金属氧酸盐，其表现出类似表面活性剂的性质，允许在氧化催化中更好地溶解有机底物；而（c）第三个涉及水中氧气的催化氧化，其中热力学稳定的催化剂在周转条件下自我缓冲。将制造几种新的多金属氧酸盐系统，如果证明其稳健，则代表一类重要的低成本氧化催化剂精细化学品生产。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污染物。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。
