9412465 Hill Emory University Dr. Craig A. Hill, Chemistry Department, Emory University, is supported by the Inorganic, Bioinorganic, and Organometallic Chemistry Program of the Chemistry Division for research into the development of heteropolyoxometallates (HPOM) as homogeneous catalysts. The transfer of oxide from an HPOM to alkanes will be developed because of its central importance to any process which involves oxidative functionalization. The factors which influence HPOM catalyzed oxidation using the environmentally advantageous hydrogen peroxide will be evaluated. As catalysts normally have a finite lifetime, new systems will be sought which will heal defects which occur in them as they operate. Finally, the ability of HPOM's to induce reactions of very unreactive materials such as diamond surfaces and to catalytically oxidize hydrogen sulfide will be determined. Oxidation reactions are very common and important in many areas of chemistry. On the industrial scale they are often plagued by environmental problems because they either use or produce toxic, potentially polluting substances. In this project a new class of environmentally benign catalysts will be developed. The basic way in which they function will be assessed and this knowledge will be used to design processes for oxidations of very non-reactive materials and for the conversion of toxic hydrogen sulfide into sulfur.

Hill博士，由化学研究部的无机，生物促和有机化学化学计划的支持，用于杂氧量计（HPOM）的开发研究部（HPOM）作为同质催化剂。将开发氧化物从HPOM到烷烃的转移，因为它对涉及氧化功能化的任何过程至关重要。将评估影响HPOM使用环境有利的过氧化氢催化氧化的因素。由于催化剂通常具有有限的寿命，因此将寻求新的系统，这些系统将治愈其操作时发生的缺陷。最后，将确定HPOM诱导非常无反应材料的反应的能力，例如钻石表面和催化氧化硫化氢。 在化学的许多领域，氧化反应非常普遍且重要。在工业规模上，它们通常会受到环境问题的困扰，因为它们要么使用或产生有毒的，潜在的污染物质。在这个项目中，将开发出新的环境良性催化剂。评估它们的基本方法，并将这些知识用于设计非常无反应材料的氧化过程，并将硫化物有毒氢转化为硫。
