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

凯斯西储大学分析和表面化学课程的Dan Scherson教授的这个项目旨在深入了解涉及氮和硫氧化物以及含氧阴离子的氧化还原反应的机制。 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原位研究。 清洁和表面改性的金属晶体表面的微观形貌也将与这些相同的光谱方法进行研究。 活性中间体的鉴定将提供对这些反应的机理的深入了解。 该研究在新型电催化剂的设计和一氧化氮等物质的特定传感器的设计中具有根本的重要性，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上的氧化和还原反应在催化和生物化学系统中都很重要，并且怀疑在反应中存在尚未鉴定的关键中间体。 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重要性。

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.
