This research project, supported in the Analytical and Surface Chemistry Program, focuses on the use of reflection absorption infrared spectroscopy to characterize adsorbed intermediates on solid surfaces. Professor Trenary and his coworkers at the University of Illinois-Chicago will examine adsorbed species containing CN multiple bonds, which result from the reactions of methane and ammonia and related compounds on well characterized platinum surfaces. High quality experimental data, combined with density functional theory calculations, will be used to make structural assignments for these adsorbed intermediates. Instrumentation and method development also forms a significant portion of the work being carried out in this project. Reflection-absorption infrared spectroscopy is a very powerful tool for the identification of adsorbed intermediates in surface reaction chemistry. Professor Trenary and his group at the University of Illinois-Chicago, with the support of the Analytical and Surface Chemistry Program, have developed an active laboratory for the development and use of this method to investigate surface reactions. Work in this project will concentrate on surface intermediates formed from the reactions of methane and ammonia adsorbed on platinum surfaces, with clear application to the understanding of HCN synthesis reactions.

这项研究项目得到了分析和表面化学计划的支持，重点是使用反射吸收红外光谱来表征固体表面上吸附的中间体。伊利诺伊大学芝加哥分校的特雷纳里教授和他的同事们将研究含有CN多重键的吸附物种，这些物种是甲烷和氨以及相关化合物在特征良好的铂表面反应的结果。高质量的实验数据，结合密度泛函理论计算，将被用来对这些被吸附的中间体进行结构指认。仪器和方法开发也构成了该项目正在进行的工作的重要部分。在表面反应化学中，反射吸收红外光谱是鉴定吸附中间体的一种非常有效的工具。伊利诺伊大学芝加哥分校的Trenary教授和他的团队在分析和表面化学计划的支持下，开发了一个活跃的实验室，用于开发和使用这种方法来研究表面反应。该项目的工作将集中在吸附在铂表面上的甲烷和氨的反应形成的表面中间体，明确地应用于理解HCN合成反应。
