This research project, supported by the Analytical and Surface Chemistry Program, focuses on the decomposition reaction of methanol on platinum electrode surfaces and on modified platinum electrode surfaces. Professor Wieckowski and his students at the University of Illinois at Urbana will use electrochemical methods combined with core-level electron energy loss spectroscopy, x-ray photoelectron spectroscopy, and a new radiochemical method to characterize the reaction mechanisms associated with these reactions. The goal of this work is to understand, and thereby prevent, those reactions that foul the electrode surface during methanol decomposition so that these sytsems can be used as practical fuel cells. This work has enormous technological potential. Studies of the decomposition reaction of the simplest alcohol, methanol, on platinum and modified platinum electrodes will be studied in this work. Over time, this reaction fouls the electrode and the reaction ceases to occur. This prevents use of methanol, an inexpensive source of energy, in fuel cells that could otherwise be used in many practical applications.

该研究项目在分析和表面化学计划的支持下，重点是甲醇在铂电极表面和改良的铂电极表面上的分解反应。 Wieckowski教授及其伊利诺伊大学Urbana的学生将使用电化学方法与核心水平的电子能量损失光谱，X射线光电光谱和新的放射化学方法相结合，以表征与这些反应相关的反应机制。 这项工作的目的是理解，从而预防甲醇分解过程中电极表面污染的反应，以便可以将这些SYTSEM用作实用的燃料电池。 这项工作具有巨大的技术潜力。 在这项工作中，将研究对铂和修饰的铂电极上最简单的酒精，甲醇的分解反应的研究。 随着时间的流逝，该反应会使电极犯规，并且反应停止发生。 这可以防止在燃料电池中使用甲醇，这是一种廉价的能源，否则可以在许多实际应用中使用。
