The Chemical Catalysis Program supports a four-way collaboration between Professors Richard Eisenberg and David W. McCamant of the University of Rochester and Michael R. Detty and David Watson of the University at Buffalo on new systems for the visible light-driven generation of hydrogen from aqueous protons, and associated photochemical and photophysical investigations to fully understand this critical transformation. The reaction corresponds to the reductive side of water splitting, which is the key reaction in artificial photosynthesis and the conversion of light into stored chemical potential energy. The research focuses on: (1) systems containing new or unstudied chromophores for light absorption and electron transfer, and catalysts for proton reduction; and (2) systems integration since the robustness and activity of different components affect each other.Abundant, environmentally-benign energy for sustainable development is one of this century's great scientific and technological challenges, and solar energy conversion is the key long-term strategy to solving this problem. Through the Chemical Catalysis Program, this collaborative research effort will contribute to the fundamental science on which future energy technology can be built and implemented. The entire concept of a hydrogen economy relies on an efficient and robust means to carry out water splitting using the sun as the primary energy source. The broader impacts of the research will manifest themselves in two major ways. First, through the research accomplished, greater knowledge about the reductive side of water splitting will be gained. For the most viable new systems for hydrogen generation, connection to a successful module for water oxidation may yield a system for solar splitting of water. Second, new scientists will be educated and trained to work in this challenging and important subject.

化学催化计划支持教授理查德艾森伯格和大卫W。罗切斯特大学的McCamant和Michael R.布法罗大学的Detty和大卫沃森对可见光驱动的水质子制氢新系统进行了研究，并进行了相关的光化学和光物理研究，以充分了解这一关键转变。 该反应对应于水分解的还原侧，这是人工光合作用和将光转化为储存的化学势能的关键反应。 研究重点是：（1）含有新的或未经研究的用于光吸收和电子转移的发色团以及用于质子还原的催化剂的体系;（2）系统集成，因为不同组件的鲁棒性和活性相互影响。丰富的、环境友好的可持续发展能源是本世纪的重大科技挑战之一，太阳能转换是解决这一问题的关键长期战略。 通过化学催化计划，这项合作研究工作将有助于基础科学，未来的能源技术可以建立和实施。 氢经济的整个概念依赖于一种高效而强大的手段，以太阳为主要能源进行水分解。 这项研究的更广泛影响将以两种主要方式表现出来。 首先，通过完成的研究，将获得更多关于水裂解还原方面的知识。 对于最可行的制氢新系统，连接到用于水氧化的成功模块可以产生用于太阳能分解水的系统。 第二，新的科学家将接受教育和培训，从事这一具有挑战性和重要性的课题。
