The Chemical Catalysis (CAT) program in the Division of Chemistry supports work on homogeneous catalysis in the laboratory of Professor Wesley Bernskoetter of the University of Missouri. The project examines new uses for carbon dioxide, which is an abundant and renewable resource. Currently, most consumer goods are produced from petrochemical. This project envisions that chemicals can be produced by combining petrochemicals and carbon dioxide. The project aims to discover catalysts that combine carbon dioxide with petrochemicals, a process called carboxylation. Many technologies could be enabled if carboxylations could be more efficient, the goal of this research. This project also aims to spread awareness of chemistry’s role in society. Hands-on training is provided to the next generation of scientists including underrepresented groups.With funding from the Chemical Catalysis (CAT) program in the Division of Chemistry, the laboratory of Professor Wesley Bernskoetter of the University of Missouri is developing new catalysts to utilize carbon dioxide as a renewable, alternative carbon source for commercial chemicals. The research targets reactions that form carbon-carbon bonds between carbon dioxide and other reactive small molecules, such as ethylene or acetylene. These processes reduce carbon dioxide while also creating valuable carboxylated products including acrylates, oxalates, and acetylene carboxylates in nearly thermoneutral reactions. Through mechanistic studies of the elementary reaction steps and structure-reactivity relationships, the project identifies the pathways for these rare transformations of the stable carbon dioxide molecule. These findings build a foundation for further design of catalysts and processes enabling efficient, scalable conversion of carbon dioxide into a wide array of more complex, higher value molecules. The Bernskoetter laboratory uses this research trains future leaders in the science and to broaden participation of underrepresented groups in chemistry as a partner of the University of Missouri McNair Scholars program.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.

化学系的化学催化（CAT）项目支持密苏里大学 Wesley Bernskoetter 教授实验室的均相催化工作，该项目研究二氧化碳的新用途，二氧化碳是目前最丰富的可再生资源。该项目设想通过将石化产品与二氧化碳结合来生产化学品，这一过程称为羧化。如果羧化可以更有效，该项目的目标还在于向下一代科学家（包括代表性不足的群体）提供实践培训。密苏里大学 Wesley Bernskoetter 教授实验室化学系的催化 (CAT) 项目是利用二氧化碳作为商业化学品的可再生替代碳源的新型催化剂，该研究的目标是开发形成碳-碳的反应。通过对基本反应步骤和结构键的机理研究，这些过程可以减少二氧化碳，同时在近乎热中性的反应中产生有价值的羧化产物，包括丙烯酸酯、草酸盐和乙炔羧酸盐。 -反应性关系，该项目确定了稳定二氧化碳分子这些罕见转化的途径，这些发现为进一步设计催化剂和工艺奠定了基础，从而实现了高效、可扩展的转化。 Bernskoetter 实验室利用这项研究来培训未来的科学领导者，并作为密苏里大学麦克奈尔学者计划的合作伙伴扩大化学领域代表性不足的群体的参与。该奖项由 NSF 授予。法定使命，并通过使用基金会的智力优点和更广泛的影响审查标准进行评估，被认为值得支持。
