项目摘要
Laser induced thermal desorption coupled with Fourier transform mass spectrometry is used as a probe of surface reaction kinetics in this project carried out with support from the Analytical and Surface Chemistry Program. Professor John Hemminger of the University of California, Irvine and his coworkers are using this method to address questions of hydrocarbon surface reaction kinetics and mechanisms. In particular, the effect of high concentrations of coadsorbed hydrogen on the initial C-H bond breaking step in the dehydrogenation of cyclohexane on Pt(111) is being explored. In addition, information about reactant overlayer configuration, and ensemble effects in hydrocarbon reactions on the platinum surface, is being obtained. This fundamental information provides a mechanistic understanding for important heterogeneous catalytic reactions. Desorption of reaction intermediates, followed by mass spectral identification of these species, is used to develop an understanding of surface reaction mechanisms in this project. The important reactions of hydrocarbons on well characterized platinum surfaces are the focus of this work, which provides fundamental understanding of catalytic reactions central to the chemical and energy production industries. The unique experimental capability in the Principal Investigator's laboratory allows a detailed description of the mechanisms and rates of these important reactions.
激光诱导热脱附与傅里叶变换质谱联用在分析和表面化学计划的支持下进行的这个项目中被用作表面反应动力学的探针。 加州大学欧文分校的John Hemminger教授和他的同事正在使用这种方法来解决碳氢化合物表面反应动力学和机制的问题。 特别是,高浓度的共吸附的氢的效果上的初始的C-H键断裂的步骤在环己烷上的Pt(111)脱氢正在探索。 此外,有关反应物覆盖层的配置,并在铂表面上的碳氢化合物反应的合奏效果的信息,正在获得。 这些基本信息为重要的多相催化反应提供了机理上的理解。反应中间体的解吸,然后对这些物质进行质谱鉴定,用于加深对该项目中表面反应机制的理解。 碳氢化合物在铂表面上的重要反应是这项工作的重点,它提供了对化学和能源生产工业核心催化反应的基本理解。 主要研究者实验室的独特实验能力允许详细描述这些重要反应的机制和速率。
