With the support of the Chemical Catalysis program in the Division of Chemistry, Professor Wesley Bernskoetter of the University of Missouri-Columbia is studying new applications for carbon dioxide in the production of commercial chemicals. A large portion of commercial chemicals used to produce consumer goods, including plastics, synthetic fibers, and medicines are derived from petrochemical sources. This project will develop new catalytic processes that combine abundant and renewable carbon dioxide resources with other reagents to provide alternative routes to valuable chemicals. The project aims to identify which features in catalyst structures control reaction selectivity in order to minimize the formation of undesired byproducts. Effective control of catalyst selectivity enables more efficient chemical synthesis and new technologies in sustainable chemical production. This project will provide practical training to a new generation of scientists, including those from historically underrepresented groups in the chemical sciences. Team members aim to increase recognition of diverse petrochemical-derived products in society and increase awareness of the need to develop more sustainable routes to consumer goods. The project partners with the University of Missouri Stevens Scholars and related programs to broaden the participation of underrepresented groups in chemistry and develop future leaders in science.Under this award, Professor Wesley Bernskoetter and his team at the University of Missouri-Columbia are studying new catalysts for valorizing carbon dioxide via coupling with ethylene. The project seeks to couple various stoichiometric combinations of carbon dioxide and ethylene to produce a range of mono- and dicarboxylate small molecules, such as acrylates, methylmalonates, succinates and adipates. These are chemicals with significant commercial value; through mechanistic studies the project seeks to establish pathways to control the selective production of carboxylate feedstocks. These studies are fundamental but have elements of use-inspired research. Thus, if successful, this research will contribute to the technology required to advance a range of current research in sustainable chemical production, including the production of fuels from CO2 and the incorporation of CO2 into renewably sourced polymers.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在化学系化学催化计划的支持下，密苏里大学哥伦比亚分校的Wesley Bernskoetter教授正在研究二氧化碳在商业化学品生产中的新应用。 用于生产消费品的大部分商业化学品，包括塑料，合成纤维和药品，都来自石化来源。 该项目将开发新的催化工艺，将联合收割机丰富的可再生二氧化碳资源与其他试剂相结合，为有价值的化学品提供替代路线。该项目旨在确定催化剂结构中的哪些特征控制反应选择性，以最大限度地减少不需要的副产物的形成。 有效控制催化剂选择性可实现更高效的化学合成和可持续化学生产的新技术。该项目将为新一代科学家提供实际培训，包括那些来自化学科学领域历史上代表性不足的群体的科学家。 团队成员的目标是提高社会对各种石化衍生产品的认可，并提高对开发更可持续的消费品路线的必要性的认识。该项目与密苏里州史蒂文斯学者和相关计划的大学合作，以扩大在化学中的代表性不足的群体的参与，并培养未来的科学领导者。在这个奖项下，教授韦斯利Bernskoetter和他的团队在密苏里大学哥伦比亚分校正在研究新的催化剂，通过与乙烯偶联稳定二氧化碳。 该项目旨在将二氧化碳和乙烯的各种化学计量组合偶联，以产生一系列单羧酸酯和二羧酸酯小分子，如丙烯酸酯、甲基丙二酸酯、琥珀酸酯和己二酸酯。 这些都是具有重要商业价值的化学品;通过机理研究，该项目旨在建立控制羧酸盐原料选择性生产的途径。 这些研究都是基础性的，但也有使用启发研究的元素。 因此，如果成功的话，这项研究将有助于推动当前可持续化学生产领域的一系列研究所需的技术，包括从CO2生产燃料和将CO2纳入可再生聚合物。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
