This award supports the collaborative efforts of Richard Glass, Dennis Evans and Dennis Lichtenberger, all at the University of Arizona, to develop synthetic catalysts for hydrogen generation inspired by hydrogenase enzymes. In their systems, a low potential redox ligand derived from methyl viologen or quinone is coupled to a di-iron system capable of reducing hydronium ions to hydrogen. The team will utilize photoelectron spectroscopy and electrochemistry augmented by theoretical calculations in an effort to understand what aspects of ligand structure are most important in tuning the redox potential and catalytic activity to optimal levels.This research may lead to new catalysts useful in hydrogen production and in fuel cells and therefore contribute to the new technologies needed for sustainable energy supplies. This project is funded through the Collaborative Research in Chemistry Program (CRC) and provides outstanding opportunities for undergraduates and graduate students to acquire knowledge and skills in very broad areas of synthesis, electrocatalysis, spectroscopy and theory. Teams of high school teachers and students from demographically diverse high schools in Tucson will also participate in this research.

该奖项支持亚利桑那大学的理查德·格拉斯 (Richard Glass)、丹尼斯·埃文斯 (Dennis Evans) 和丹尼斯·利希滕伯格 (Dennis Lichtenberger) 的合作努力，以开发受氢化酶启发的合成氢催化剂。在他们的系统中，衍生自甲基紫精或醌的低电势氧化还原配体与能够将水合氢离子还原成氢的双铁系统偶联。该团队将利用光电子能谱和电化学通过理论计算增强，努力了解配体结构的哪些方面对于将氧化还原电位和催化活性调整到最佳水平最重要。这项研究可能会产生可用于制氢和燃料电池的新催化剂，从而有助于可持续能源供应所需的新技术。该项目由化学合作研究计划 (CRC) 资助，为本科生和研究生提供了获取合成、电催化、光谱学和理论等广泛领域知识和技能的绝佳机会。来自图森人口多元化高中的高中教师和学生团队也将参与这项研究。
