伊利诺伊大学芝加哥分校化学系的Trenary教授和他的同事正在使用时间分辨反射吸收红外光谱法，结合时间依赖性氢剂量和热解吸光谱法，来研究基本反应步骤的机制。 特别是，在分析和表面化学计划的支持下，他们正在研究铂和钌表面上吸附的NH，CN和C2物种的氢化和脱氢机制。 这些研究的基本信息将有助于更好地了解这些重要的催化过程。 详细描述基本表面反应动力学的能力是合理设计催化材料和工艺的关键。 在分析和表面化学项目的支持下，伊利诺伊大学芝加哥分校的Trenary教授和他的团队正在进行实验，提供这些详细的信息。 使用红外光谱加上随时间变化的计量方法，重要的加氢和脱氢反应的详细机制正在获得。 这些信息在多相催化等重要技术领域具有广泛的影响。

Professor Trenary and his coworkers in the Department of Chemistry at the University of Illinois-Chicago are using time resolved reflection absorption infrared spectroscopy, coupled with time dependent hydrogen dosing and thermal desorption spectroscopy, to examine the mechanisms of fundamental reaction steps on well characterized catalytic surfaces. In particular, with the support of the Analytical and Surface Chemistry Program, they are examining the mechanisms of hydrogenation and dehydrogenation of adsorbed NH, CN, and C2 species on platinum and ruthenium surfaces. Fundamental information from these studies will be useful in developing a better understanding of these important catalytic processes. The ability to describe in detail the kinetics of fundamental surface reactions is key to rationally designing catalytic materials and processes. With the support of the Analytical and Surface Chemistry Program, Professor Trenary and his group at the University of Illinois-Chicago are carrying out experiments that provide this detailed information. Using infrared spectroscopy coupled with time dependent dosing methods, the detailed mechanisms of important hydrogenation and dehydrogenation reactions are being obtained. This information has broad impact in technologically important fields such as heterogeneous catalysis.
