The electrocatalytic oxidation of small organic molecules forms the focus of the research of Professor Korzeniewski at Texas Tech University. This project, supported by the Analytical and Surface Chemistry Program, addresses the kinetics of formation of intermediates in the electrocatalytic oxidation of methanol using chromatography coupled with small volume electrolysis methods. The activation of water in these electrolytic processes is probed by monitoring the effect of the activation on the oscillatory voltammetry of CO on the platinum electrode. Information from these studies will enable the improved design of direct methanol fuel cells as well as the use of electrocatalysis for the destruction of organic contaminants in groundwater. A detailed understanding of the electrocatalytic oxidation of small organic molecules is important to the development of fuel cells and processes for remediation of contaminated groundwater sources. This research project studies the mechanisms of these processes using a combination of chromatographic detection of reaction intermediates and voltammetric probes of electrode kinetics.

有机小分子的电催化氧化是德克萨斯理工大学Korzeniewski教授的研究重点。 该项目由分析和表面化学计划支持，采用色谱法结合小体积电解法研究甲醇电催化氧化过程中中间体形成的动力学。 在这些电解过程中的水的活化探测通过监测的CO的振荡伏安法在铂电极上的活化的效果。 从这些研究中获得的信息将使直接甲醇燃料电池的设计得到改进，以及利用电催化来破坏地下水中的有机污染物。 详细了解有机小分子的电催化氧化对燃料电池的发展和污染地下水源的修复过程具有重要意义。 本研究计画结合反应中间体的层析检测与电极动力学的伏安探针，研究这些过程的机制。
