The Chemical Catalysis Program supports the research of Professors Krishnan Rajeshwar and Frank W. Foss Jr. of the University of Texas at Arlington to collaborate with Professor Yaron Paz of Technion - Israel Institute of Technology in Israel to design and develop more efficient photocatalytic assemblies via the assembly of multiple components with complementary functions in a composite architecture. This International Collaboration in Chemistry (ICC) project employs components that enhance electron transport in assemblies built from stable metal oxide semiconductors, efficient electron mediators, and robust and tunable flavin organocatalysts. The team synthetically tailors and assembles individual organic and inorganic chemical components to arrive at more efficient hybrid photocatalyst assemblies. These photocatalytic systems utilize molecular assemblies designed from earth abundant, inexpensive, and benign chemicals to create new processes for photochemical catalysis. This project includes international and cooperative research and education enabling a concerted focus on basic research questions related to photocatalytic assemblies that can convert sunlight into usable energy. The US investigators enable students at the Center for African American Studies and the AACCESS program, a program that provides need-based scholarships for tuition at UT Arlington to lower-income students at local Tarrant County Community Colleges. This project provides opportunities for high school, undergraduate and graduate students for hands-on experiences, exposing them to the collaborative nature of international research.

化学催化项目支持Krishnan Rajeshwar教授和Frank W.小福斯美国德克萨斯大学阿灵顿分校的科学家与以色列理工学院的Yaron Paz教授合作，通过在复合结构中组装具有互补功能的多个组件，设计和开发更高效的光催化组件。 这个国际化学合作（ICC）项目采用的组件可以增强由稳定的金属氧化物半导体，高效的电子介体和稳健且可调的黄素有机催化剂构建的组件中的电子传输。 该团队综合定制和组装单个有机和无机化学成分，以获得更高效的混合光催化剂组件。 这些光催化系统利用从地球上丰富的，廉价的，和良性的化学品设计的分子组件，以创造新的光催化过程。 该项目包括国际合作研究和教育，使人们能够共同关注与光催化组件相关的基础研究问题，这些组件可以将阳光转化为可用能源。 美国调查人员使非裔美国人研究中心和AACCESS项目的学生能够在当地塔兰特县社区学院为UT阿灵顿的低收入学生提供基于需求的奖学金。 该项目为高中生、本科生和研究生提供了实践经验的机会，使他们接触到国际研究的协作性质。
