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.

化学系和国际科学与工程办公室的化学催化计划将支持埃默里大学的Craig Hill教授和他的同事与英国格拉斯哥大学的Lee Cronin教授合作，开发可见光驱动将水还原为二氢的催化剂，并构建由光敏剂阳离子和多金属氧酸盐(POM)催化剂组成的新型多功能、高比表面积微管。英国工程和物理科学研究理事会(EPSRC)将支持克罗宁教授和他的同事的研究。用这些微管修饰的新型光电阴极将被用来高效地光产生氢气。光敏剂Ru离子与POM催化剂的相互作用将在溶液和固体两种情况下进行研究。这项研究的开展需要仪器以及英国实验室现有的纳米和微制造基础设施和材料表征技术。希尔教授实验室的光催化和机理研究的设备和知识将与英国实验室共享。将使用Ru光敏剂阳离子和多金属氧酸盐催化剂开发用于从水和阳光中光产生氢气的新材料。这项研究将在与绿色能源化学以及太阳能燃料研究的催化、材料和光谱方面相关的技术、智力和实践挑战方面培训年轻学者。历史上的黑人学院和大学以及主要是本科院校的调查人员和学生将被邀请参加小组会议和年度会议。
