International Collaboration in Chemistry - Modular Microtubular Architectures for Photo-driven Generation of Dihydrogen and Dioxygen from Water

化学系和国际科学与工程办公室的化学催化项目将支持埃默里大学的克雷格·希尔教授及其同事与英国格拉斯哥大学的李·克罗宁教授合作开发催化剂，用于可见光驱动将水还原为二氢，并构建一种新型多功能，由光敏剂阳离子和多金属氧酸盐（POM）催化剂组成的高表面积微管。英国工程与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。用这些微管修饰的新型光电阴极将用于二氢的高效光生成。光敏剂钌阳离子与POM催化剂之间的相互作用将在溶液和固体状态下进行研究。这项研究的起诉需要仪器和纳米和微加工基础设施和材料表征技术目前在英国实验室。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。利用钌光敏剂阳离子和多金属氧酸盐催化剂，将开发用于从水和阳光中产生氢的新材料。这项研究将在绿色能源化学以及太阳能燃料的催化、材料和光谱学方面的研究方面，对年轻学者进行技术、知识和实践方面的培训。历史上黑人学院和大学以及主要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。

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.
