The Chemical Catalysis Program in the Division of Chemistry and the Office of International Science and Engineering will support Professor Craig Hill and his coworkers at Emory University to work in conjunction with Professor Lee Cronin at the University of Glasgow in the UK to develop catalysts for the visible-light-driven reduction of water to dihydrogen and the construction of a new type of multifunctional, high-surface-area microtube composed of photosensitizer cations and polyoxometalate (POM) catalysts. UK's Engineering and Physical Sciences Research Council (EPSRC) will support the research of Professor Cronin and his coworkers. New photocathodes modified with these microtubes will be constructed for the efficient photogeneration of dihydrogen. Interactions between photosensitizer ruthenium cations and POM catalysts will be studied in both solution and the solid state. The prosecution of this research requires instruments and nano- and microfabrication infrastructure and materials characterization techniques present in the UK laboratory. Equipment and knowledge for photocatalysis and mechanistic investigations in Professor Hill's laboratory will be shared with the UK laboratory.New materials for the photogeneration of hydrogen from water and sunlight will be developed using ruthenium photosensitizer cations and polyoxometalate catalysts. The research will train young scholars in the technical, intellectual and practical challenges associated with green energy chemistry together with the catalysis, materials, and spectroscopic aspects of solar fuels research. Investigators and students at Historically Black College and Universities and Primarily Undergraduate Institutions will be invited to attend group meetings and annual conferences.

化学分校和国际科学与工程办公室的化学催化计划将支持克雷格·希尔（Craig Hill）教授及其在埃默里大学（Emory University）的同事与英国格拉斯哥大学的李·克罗宁（Lee Cronin）教授合作，为可见的催化剂开发催化剂 - 将水还原为二氢，以及由光敏剂阳离子和聚氧盐（POM）催化剂组成的新型多功能高表面环境微管的新型。 英国的工程和物理科学研究委员会（EPSRC）将支持克罗宁教授及其同事的研究。 将使用这些微管修饰的新光子座将用于二氢基因的有效光生成。 光（光敏剂弦琴阳离子与POM催化剂）之间的相互作用将在溶液和固态中进行研究。 对这项研究的起诉需要英国实验室中存在的工具以及纳米和微生物基础设施和材料表征技术。 Hill教授实验室的光催化和机械研究的设备和知识将与英国实验室共享。将使用芳族光敏剂阳离子和多氧计催化剂开发用于水和阳光的氢的新材料。 这项研究将培训年轻的学者在与绿色能源化学相关的技术，智力和实践挑战，以及太阳能燃料研究的催化，材料和光谱方面。 历史悠久的黑人学院和大学以及主要是本科机构的调查人员和学生将邀请参加小组会议和年度会议。
