Earth Abundant Metal-Doped Covalent Organic Frameworks for Heterogeneous Catalysis

开发可持续催化剂是化学领域的一个重要研究课题。可持续催化剂可加速原材料转化为有价值的化学品，同时提高化学反应的安全性，并最大限度地减少对环境的负面影响。在这个项目中，俄亥俄州州立大学（OSU）的Psaras McGrier教授正在使用先进的结晶多孔聚合物制备可持续催化剂。这些催化剂用于将植物材料（生物质）转化为化学燃料，以及从石油原料中去除硫，以尽量减少造成污染的副产品的排放。 McGrier教授正在利用OSU的几个教育和推广计划，以帮助增加年轻，代表性不足的少数民族在STEM领域的参与。这些活动包括参加科学冠军早餐（BoSC），这是一个OSU计划，允许来自哥伦布市学校的代表性不足的中学生有机会参观和了解更多关于各种尖端研究项目的信息。McGrier教授还为俄亥俄州哥伦布的高中生组织了一个研究实习项目。在这个由化学系化学催化项目资助的项目中，俄亥俄州州立大学（OSU）的Psaras McGrier教授正在开发可持续的催化剂，该催化剂可以进行交叉偶联反应，并使用共价有机框架（COF）激活惰性碳-杂原子键。正在研究含有三角形、π电子共轭、脱氢苯并轮烯（DBA）金属位点的苯并双恶唑（BBO）连接的基于COF的催化剂。目标是获得可用于活化惰性碳-氧（C-O）和碳-硫（C-S）键的BBO-COF。芳基C-O键的活化提供了一个机会，不仅使用芳基醚来提高正交交叉偶联反应的原子效率和安全性，而且还将木质素基生物质转化为脱氧化学燃料。C-S键的活化和还原可用于石油原料的脱硫以最小化有害硫氧化物副产物的排放。该提案包括几个教育和外展计划，以帮助增加年轻的代表性不足的少数民族在STEM领域的参与。这些活动包括参加科学冠军早餐（BoSC），这是一个OSU STEM计划，允许来自哥伦布市学校的代表性不足的中学生有机会参观和了解更多关于各种尖端研究项目的信息。 McGrier教授还为俄亥俄州哥伦布的高中生组织了一项研究实习计划。该奖项反映了NSF的法定使命，并被认为值得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来支持。

Developing sustainable catalysts is an important research subject in chemistry. Sustainable catalysts speed up the conversion of raw materials to valuable chemicals while they improve the safety of chemical reactions and minimize negative impacts to the environment. In this project, Professor Psaras McGrier of The Ohio State University (OSU) is preparing sustainable catalysts using an advanced class of crystalline porous polymers. These catalysts are used to convert plant materials (biomass) to chemical fuels as well as to remove sulfur from petroleum feedstocks to minimize the emission of pollution-causing by-products. Professor McGrier is utilizing several education and outreach programs at OSU to help increase the participation of young, underrepresented minorities in the STEM fields. These activities include participation in the Breakfast of Science Champions (BoSC), an OSU program that allows underrepresented middle school students from Columbus City Schools the opportunity to visit and learn more about various cutting edge research projects. Professor McGrier is also organizing a research internship program for high school students from Columbus, OH.In this project funded by the Chemical Catalysis program of the Chemistry Division, Professor Psaras McGrier of The Ohio State University (OSU) is developing sustainable catalysts that perform cross-coupling reactions and activate inert carbon-heteroatom bonds using covalent organic frameworks (COFs). Benzobisoxazole (BBO)-linked COF-based catalysts that contain triangularly-shaped, pi-electron conjugated, dehydrobenzoannulene (DBA) metal sites are being studied. The goal is to obtain BBO-COFs that can be utilized to activate inert carbon-oxygen (C-O) and carbon-sulfur (C-S) bonds. The activation of aryl C-O bonds offers an opportunity to not only use aryl ethers to improve the atom-efficiency and safety of orthogonal cross-coupling reactions, but also to convert lignin-based biomass to deoxygenated chemical fuels. The activation and reduction of C-S bonds is useful for the desulfurization of petroleum feedstocks to minimize the emission of harmful sulfur oxide by-products. This proposal includes several education and outreach programs to help increase the participation of young underrepresented minorities in the STEM fields. These activities include the participation in the Breakfast of Science Champions (BoSC), an OSU STEM program that allows underrepresented middle school students from Columbus City Schools the opportunity to visit and learn more about various cutting edge research projects. Professor McGrier also organizes a research internship program for high school students from Columbus, OH.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.
