项目摘要

The Chemical Structure, Dynamics and Mechanisms Program and the Chemical Measurements and Imaging Program in the Chemistry Division at the National Science Foundation support Professor Dennis Lichtenberger of the University of Arizona, for photoelectron spectroscopy studies of Fe-S clusters as related to solar fuels (H2) production. The goal of this work is to understand the fundamental principles of electron transfer reactions of such catalysts, synthesized in the PI's laboratory and in others. Evaluation of Marcus theory parameters for these reactions will lead to a better understanding of catalyst structure and function at the molecular level, and develop criteria for higher efficiency solar fuels generators. Broader impacts of the research include driving innovation in solar energy applications, and contributing to scientific infrastructure by developing next-generation instrumentation and methods for photoelectron spectroscopy of large molecules. The Lichtenberger laboratory will provide access to these capabilities for other researchers, and develop curricula for undergraduate education. This laboratory has had significant success in recruiting undergraduate students, women, and underrepresented minorities into the program, including those from the Hispanic and Native American populations in the Tucson area.

美国国家科学基金会化学部的化学结构，动力学和机制计划以及化学测量和成像计划支持亚利桑那大学的Dennis Lichtenberger教授进行与太阳能燃料（H2）生产相关的Fe-S团簇的光电子能谱研究。这项工作的目标是了解在PI实验室和其他地方合成的此类催化剂的电子转移反应的基本原理。对这些反应的Marcus理论参数的评估将导致在分子水平上更好地理解催化剂的结构和功能，并为更高效的太阳能燃料发电机制定标准。该研究的更广泛影响包括推动太阳能应用的创新，并通过开发下一代大分子光电子能谱仪和方法为科学基础设施做出贡献。 Lichtenberger实验室将为其他研究人员提供这些能力，并为本科教育开发课程。该实验室在招募本科生，妇女和代表性不足的少数民族进入该计划，包括那些来自图森地区的西班牙裔和美洲原住民人口取得了显着的成功。
