The Adsorption and Reactions of Methyl Radicals on Solid Surfaces

本研究项目在分析和表面化学计划的支持下，研究了小分子烷基在表征良好的表面上的表面化学。斯塔尔教授开发了一种新的自由基源，用于在具有良好特性的钼和铁的固体表面产生和沉积烷基自由基。将使用各种超高真空光谱探针来探索被吸附物种的氧化和自由基偶联化学。还将对自由基吸附的详细动力学进行研究。要了解碳氢化合物催化的复杂表面化学，一种方法是研究可能的反应中间体的详细表面化学。本研究项目使用这种方法制备自由基烷基中间体，并将它们沉积在具有良好特性的表面上。然后研究了这些中间体的化学，提供了对碳氢化合物催化机理的详细了解。

This research project, supported by the Analytical and Surface Chemistry Program, is concerned with the surface chemistry of small alkyl radicals on well characterized surfaces. Professor Stair has developed a novel radical source which is used to produce and deposit alkyl radicals on well characterized solid surfaces of molybdenum and iron. The oxidative and radical coupling chemistry of the adsorbed species will be explored using a variety of ultra-high vacuum spectroscopic probes. Studies of the detailed dynamics of radical adsorption will also be carried out. %%% One approach to the understanding of the complex surface chemistry of hydrocarbon catalysis is to investigate the detailed surface chemistry of possible reaction intermediates. This research project uses this approach by preparing radical alkyl intermediates and depositing them on a well characterized surface. The chemistry of these intermediates is then examined, providing a detailed understanding of the mechanism of hydrocarbon catalysis.
