Photon and Electron Driven Processes at Adsorbate-Metal Interfaces

在分析化学和表面化学的一般领域中，研究的重点是表面化学。这项工作有望使人们理解光子或电子的能量转化为电子激发的机制，从而导致附着在金属表面的化学物质之间的键断裂。这样的实验提高了我们对表面化学的理解，从而可以产生更好的催化剂，从而产生更便宜、更好的化学产品。金属如铂和银将被用作底物，烷基卤化物将被用作附着在这些底物上的物种的模型系统。将研究共吸附物质（如氧和乙烯）之间的光子诱导反应，以及激光诱导化学吸附物质在金属表面的解吸效应。

The research, in the general area of Analytical and Surface Chemistry, focuses on surface chemistry. The work promises to lead to an understanding of the mechanisms by which the energy of a photon or electron is converted to electronic excitation that leads to bond breaking whithin chemical species attached to a metal surface. Such experiments improve our understanding of surface chemistry which can lead to better catalysts and thus cheaper and better chemical products. Metals such as platinum and silver will be used as substrates and alkyl halides used as model systems for species attached to these substrates. Photon-induced reactions among coadsorbed species (such as oxygen and ethylene) will be examined, as will the effect of laser-induced desorption of chemisorbed species on the metal surface.
