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.

无机，生物无机和有机化学计划的这一奖项支持德克萨斯州A M大学化学系的Donald Darensbourg教授开发用于从二氧化碳和环氧化物生产聚碳酸酯的基质/催化剂系统的研究。将确定先前开发的使用环氧环己烷作为底物的苯氧化锌催化剂的详细作用机理，并用于设计新的催化剂。本研究的目的是开发新的有效的催化剂，使二氧化碳和容易获得的环氧乙烷和环氧丙烷能够生产聚碳酸酯，这是一类重要的工业聚合物。这些催化剂将允许直接利用温室气体二氧化碳，并取代目前基于生物素的技术。光气具有很强的毒性，这种工艺将更加环保。一些不同的学生，无论是研究生和本科生，将接受广泛的培训，工业和学术生涯。
