This award in the Inorganic, Bioinorganic and Organometallic Chemistry program supports research on the development of substrate/catalyst systems for the production of polycarbonates from carbon dioxide and epoxides, by Professor Donald Darensbourg of the Department of Chemistry at Texas A&M University. The detailed mechanism of action of previously-developed zinc phenoxide catalysts using cyclohexene oxide as the substrate will be determined and used to design new catalysts. The use of double metal cyanides of zinc and cobalt or iron will be emphasized.The goal of this research is to develop new and effective catalysts which can produce polycarbonates, a commercially important class of polymers, from carbon dioxide and readily available ethylene and propylene oxides. These catalysts will permit the direct utilization of the greenhouse gas carbon dioxide as well as replacement of the current phosgene-based technology. Phosgene is highly toxic, and this process will be more environmentally friendly. A number of diverse students, both graduate and undergraduate, will receive broad training for both industrial and academic careers.

该奖项在无机，生物有机和有机金属化学计划中支持了有关德克萨斯州A＆M大学化学系的Donald Darensbourg教授的基质/催化剂系统的开发，用于从二氧化碳和环氧化物中生产二氧化碳和环氧化物的多碳酸盐。将使用环己烯氧化物作为基材作为底物的先前开发的锌氧化锌催化剂的详细作用机理，并将用于设计新的催化剂。将强调使用锌和钴或铁的双金属氰化物。这项研究的目的是开发新的有效的催化剂，这些催化剂可以产生多氧化物，从二氧化碳和易于使用的乙烯和丙烯氧化物产生一类重要的聚合物类别。这些催化剂将允许直接利用温室气二氧化碳以及更换当前基于Phosgene的技术。 Phosgene具有剧毒，此过程将更加环保。许多不同的学生，包括研究生和本科生，都将为工业和学术职业接受广泛的培训。
