Nitrate Electroreduction and Molecular Structures on Electrode Surfaces

Andrew A.伊利诺伊大学厄巴纳-香槟分校的Gewerth得到了化学系分析和表面化学项目的支持，以研究与两种电极过程相关的结构和反应性。 第一个涉及在裸露和未覆盖的电极表面上硝酸盐还原的催化作用。 第二个检查的结构，溶剂和其他分子的裸露和单层修饰电极表面。吸附在电极表面上的分子的信息将获得与电池的光谱，显微镜和电化学技术结合理论计算。 从这些研究中得到的基本信息将影响电化学的所有领域。 对电极表面的结构和反应性的更好理解会影响技术过程，如修复、腐蚀、沉积、能量储存和催化等。 这项工作是跨学科研究培训的工具。 来自代表性不足群体的学生将得到指导，并将在当地学校进行科学和化学演示。

Professor Andrew A. Gewirth of the University of Illinois at Urbana-Champaign is supported by the Analytical and Surface Chemistry Program in the Division of Chemistry to examine the structure and reactivity associated with two types of electrode processes. The first involves the catalysis of nitrate reduction on bare and bimetallic electrode surfaces. The second examines the structure of solvents and other molecules on bare and monolayer-modified electrode surfaces. Information on molecules adsorbed on electrode surfaces will be obtained with a battery of spectroscopic, microscopic, and electrochemical techniques in combination with theoretical calculations. Fundamental information resulting from these studies will impact all areas of electrochemistry. Improved understanding of the structure and reactivity of electrode surfaces impacts technological processes as diverse and important as remediation, corrosion, deposition, energy storage, and catalysis. The work serves as a vehicle for interdisciplinary research training. Students from underrepresented groups will be mentored, and hands-on science and chemical demonstrations will be performed in local schools.
