The Electrochemistry of Nitrogen and Sulfur Oxides: In Situ Spectroscopic Studies

这个项目由凯斯西储大学的Dan Scherson教授在分析和表面化学项目中进行，旨在深入了解水电解质中涉及氮、硫氧化物和氧离子的氧化还原反应机制。这些反应的不可逆吸附催化剂将通过使用不同的表面光谱进行原位研究。清洁和表面修饰的金属晶体表面的微形貌也将用相同的光谱方法进行研究。鉴定反应中间体将有助于深入了解这些反应的机理。这项研究对于设计新的电催化剂和设计特定的传感器（如一氧化氮）具有重要的基础意义，一氧化氮已被证明具有广泛的生物活性。氮和硫氧化物在电极表面的氧化和还原反应在催化和生化系统中都很重要，人们一直怀疑在反应中存在尚未确定的关键中间体。凯斯西储大学的Scherson教授和他的团队将使用表面光谱方法来识别这些中间体并评估它们的催化作用。

This project by Professor Dan Scherson of Case Western Reserve University in the Analytical and Surface Chemistry program is designed to gain insight into the mechanisms of redox reactions involving nitrogen and sulfur oxides and oxyanions in aqueous electrolytes. Irreversibly adsorbed catalysts for these reactions will be studied in situ by use of different surface spectroscopies. The microtopography of clean and surface modified metal crystal surfaces will also be studied with these same spectroscopic methods. Identification of the reactive intermediates will provide insight into the mechanisms of these reactions. The study is of fundamental importance in the design of new electrocatalysts, and in the design of specific sensors for species such as nitric oxide, which has been shown to have wide-ranging biological activity.Oxidation and reduction reactions of nitrogen and sulfur oxides on electrode surfaces is important in catalysis as well as in biochemical systems, and it has been suspected that there are key intermediates in the reaction that are not yet identified. Professor Scherson and his group at Case Western Reserve University will use surface spectroscopic methods to identify these intermediates and assess their catalytic importance.
