AbstractCHE-0603675Gewirth/IllinoisWith the support of the Analytical and Surface Chemistry Program, Professor Gewirth and his colleagues in the Department of Chemistry at the University of Illinois at Urbana-Champaign, are examining the mechanisms of electro-reduction of peroxide and nitrate at modified metal electrode surfaces. Using scanning tunneling microscopy, vibrational spectroscopy, and electrochemical methods, they are investigating these electro-reduction processes. Sum frequency generation spectroscopy is being applied to the study of the structure of the electrochemical double layer. Fundamental information from these studies will impact the design of electrocatalytic systems and nitrate sensors. The work serves as an excellent vehicle for interdisciplinary research training. Professor Gewirth and his coworkers at Illinois are using spectroscopic methods, scanning probe microscopy, and electrochemical probes to examine the mechanisms of nitrate reduction on electrode surfaces. Using non-linear spectroscopic methods, they are also probing the detailed structure of the electrolyte-electrode interface. The fundamental information obtained in these studies is useful in the design of sensor systems, and electrocatalytic materials.

在分析和表面化学项目的支持下，伊利诺伊大学厄巴纳-香槟分校化学系的Geetheth教授和他的同事们正在研究修饰金属电极表面上过氧化物和硝酸盐的电还原机理。 使用扫描隧道显微镜，振动光谱和电化学方法，他们正在研究这些电还原过程。 和频产生光谱技术正被应用于电化学双电层结构的研究。 这些研究的基本信息将影响电催化系统和硝酸盐传感器的设计。 这项工作是跨学科研究培训的一个很好的工具。伊利诺伊州的Gewerth教授和他的同事正在使用光谱方法，扫描探针显微镜和电化学探针来研究电极表面硝酸盐还原的机制。 使用非线性光谱方法，他们还探测了电解质-电极界面的详细结构。 在这些研究中获得的基本信息是有用的传感器系统的设计，和电催化材料。
