The Chemical Catalysis Program in the Chemistry Division at the National Science Foundation supports Professor Donald Darensbourg of Texas A & M University, for the development of new catalysts for the copolymerization of carbon dioxide and oxiranes/oxetanes. The goals of this research are to use mechanistic and kinetic measurements to optimize catalyst structure, and to assess the potential of the resulting copolymers as biodegradable materials. This important class of catalyst and the copolymers themselves are important in terms of renewable chemical resources and for their proposed use as biodegradable materials.Broader impacts of the research include the Darensbourg group developing catalytic reactions that can take one of the by-products of fossil fuel combustion, CO2, and use it in reactions to produce new materials. By using only catalytic amounts of compound in these reactions, an "atom economical approach" will be realized. Furthermore, the resulting compounds are likely to be biodegradable, with potential applications in medicine and physiology. The PI's laboratory has developed a national reputation for integrating research with undergraduate education through an REU program.

美国国家科学基金会化学部的化学催化项目支持德克萨斯农工大学的唐纳德·达伦斯堡教授开发用于二氧化碳和环氧乙烷/氧杂环丁烷共聚的新型催化剂。这项研究的目标是利用机械和动力学测量来优化催化剂结构，并评估所得共聚物作为可生物降解材料的潜力。这一类重要的催化剂和共聚物本身对于可再生化学资源及其作为可生物降解材料的拟议用途非常重要。该研究的更广泛影响包括达伦斯堡小组开发了可以利用化石燃料副产品之一的催化反应燃烧产生二氧化碳，并在反应中使用它来生产新材料。通过在这些反应中仅使用催化量的化合物，将实现“原子经济方法”。此外，所得化合物可能是可生物降解的，在医学和生理学方面具有潜在的应用前景。 PI 的实验室因通过 REU 项目将研究与本科教育相结合而享誉全国。
