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）项目支持密苏里州大学教授Wesley Bernskoetter实验室的均相催化工作。 该项目研究了二氧化碳的新用途，二氧化碳是一种丰富的可再生资源。目前，大多数消费品都是由石化产品生产的。该项目设想可以通过将石化产品和二氧化碳结合来生产化学品。该项目旨在发现将联合收割机二氧化碳与石化产品结合的催化剂，这一过程称为羧化。如果羧化可以更有效，许多技术可以实现，这是本研究的目标。 该项目还旨在宣传化学在社会中的作用。在化学系化学催化（CAT）项目的资助下，密苏里州大学Wesley Bernskoetter教授的实验室正在开发新的催化剂，以利用二氧化碳作为商业化学品的可再生替代碳源。 这项研究的目标是在二氧化碳和其他活性小分子（如乙烯或乙炔）之间形成碳-碳键的反应。 这些方法减少了二氧化碳，同时还在近热中性反应中产生有价值的羧化产物，包括丙烯酸酯、丙烯酸酯和乙炔羧酸酯。 通过对基元反应步骤和结构-反应性关系的机理研究，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，这些催化剂和工艺能够将二氧化碳高效、可扩展地转化为各种更复杂、更高价值的分子。 作为密苏里州麦克奈尔学者计划的合作伙伴，Bernskoetter实验室利用这项研究培养未来的科学领导者，并扩大化学领域代表性不足的群体的参与。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
