The Chemical Catalysis Program supports Professor Richard Glass and his coworkers at the University of Arizona for investigations designed to develop cheap and efficient catalysts for storing energy from electricity in chemical bonds, particularly for the production of H2 from water. Design of catalysts inspired by exceptionally efficient hydrogenase enzymes containing earth abundant Fe and Ni centers are the focus of this work. New basic science in which organic redox centers are coupled with diiron and bimetallic catalytic centers will be explored. Complementary synthetic, spectroscopic characterization, and electrochemical evaluation studies will be carried out. Understanding of intramolecular electron-transfer will result from the mechanistic approach taken in this work. The development of novel catalytic materials, coupled with an understanding of how these materials operate in the solar energy driven generation of hydrogen, will result from these studies. These new materials could have a major impact on alternative energy production, and on the supply of clean sources of energy.

化学催化计划支持亚利桑那大学的理查德·格拉斯教授和他的同事进行研究，旨在开发廉价有效的催化剂，用于将电能储存在化学键中，特别是用于从水中生产H2。设计的催化剂的灵感来自非常有效的氢化酶含有地球丰富的铁和镍中心是这项工作的重点。将探索有机氧化还原中心与二价铁和二价铁催化中心耦合的新基础科学。 将进行补充合成、光谱表征和电化学评价研究。分子内的电子转移的理解将导致在这项工作中采取的机制的方法。新的催化材料的开发，以及对这些材料如何在太阳能驱动的氢气产生中运作的理解，将来自这些研究。 这些新材料可能对替代能源生产和清洁能源的供应产生重大影响。
