In this project funded by the Chemical Catalysis program of the Chemistry Division, Professor Christopher C. Scarborough of Emory University is developing novel catalysts for oxidation reactions. The catalytic transformation generates commodity chemicals at significantly diminished environmental and economic cost compared to current industrial routes. The catalysts are novel cluster catalysts derived from earth abundant elements and are designed to use oxygen from ambient air to drive the oxidation reactions. Detailed studies correlating structure, reactivity, and catalytic performance are ongoing with the long-term goal of generating optimal catalysts for replacing energy-intensive industrial processes, in particular the Hock Process that is currently employed in the annual production of seven billion kilograms of phenol. This project seeks to develop novel inorganic catalysts, built around Ca and Cu centers with the potential to achieve arene oxidation, initially with hydrogen peroxide, and eventually, if successful, with molecular oxygen. This approach to phenol oxidation represents a fundamentally new direction, and as such, the Division sees this as an important direction to explore from the point of view of developing sustainable chemistry, in general, and new catalytic processses with earth abundant metals, in particular. Professor Scarborough's outreach efforts are designed to improve inclusion of underrepresented groups in STEM disciplines and to inspire high-achieving students to pursue advanced studies in chemistry. He has established a collaborative symposium for inorganic chemists in the greater Atlanta area that brings together faculty, postdoctoral scholars, and students from colleges and universities across the region, with participation from primarily undergraduate institutions (including those serving under-represented groups in STEM fields) and major research institutions. Professor Scarborough is working to inspire young people to pursue advanced studies in STEM disciplines through a mentorship program that trains gifted high school students through laboratory internships as well as through participation in a team that is revising the undergraduate chemical curriculum.

在该项目由化学部化学催化计划资助的项目中，埃默里大学的克里斯托弗·史卡伯勒教授正在开发新颖的催化剂来氧化反应。与当前的工业路线相比，催化转化的环境和经济成本显着下降。催化剂是源自地球丰富元素的新型簇催化剂，旨在利用环境空气中的氧气驱动氧化反应。详细的研究将结构，反应性和催化性能与生成最佳催化剂的长期目标相关联，以取代能源密集型工业过程，尤其是目前在每年生产70亿公斤苯酚中使用的HOCC过程。该项目旨在开发新型的无机催化剂，该催化剂围绕CA和CU中心建立，有可能实现Arene氧化，最初是用过氧化氢氧化的，最终（如果成功），则使用分子氧。这种苯酚氧化方法是从根本上新的方向，因此，该划分将其视为从开发可持续化学的角度探索的重要方向，通常是具有地球丰富金属的新催化过程。 士嘉堡教授的外展工作旨在改善在STEM学科中代表性不足的群体的包容，并激发高成就的学生从事化学的高级研究。他为大亚特兰大地区的无机化学家建立了合作研讨会，将教职员工，博士后学者和来自该地区的大学和大学的学生汇集在一起​​，其中主要是本科机构的参与（包括那些在STEM领域中服务不足的群体和主要研究机构的人）和主要研究机构。斯卡伯勒教授正在努力通过一项指导计划来激发年轻人在STEM学科中进行高级研究，该计划通过实验室实习和参与修改本科化学课程的团队来训练有天赋的高中生。
