Mark Schell of Southern Methodist University is supported by the Theoretical and Computational Chemistry Program to study the electrochemical oxidation of oxygenated organics, using experimental and theoretical approaches to explore these processes and the nonlinear behavior that they exhibit. Most of the effort will focus on formic acid oxidation. Objectives are to characterize the different ways that anions affect the oxidation process, to find the origin of these effects, and to investigate whether these effects can be used to probe electrochemical mechanisms. Substantial new understanding is expected to be gained by studying anion interactions with surrounding stationary and transient neighbors. Research outcomes are expected to enhance the understanding of oxidation reactions that are important in fuel cell applications. This project will provide valuable introductory research opportunities to undergraduate students in both theoretical and experimental chemistry. The electrocatalyzed oxidations of oxygenated organic compounds are important because of their applications in fuel cells. It is a goal of many academic and industrial researchers to improve the viability of commercial ambient methanol-air fuel cells to replace conventional fossil fuel sources. This goal is important because greenhouse gases are increasing in the environment, and as well because future fossil fuel energy shortages are probable. A practical objective of this research is to enhance methanol oxidation by methods similar to those used to enhance formic acid oxidation. Enhancing methanol oxidation translates into more efficient fuel cells.

南方卫理公会大学的Mark Schell由理论和计算化学计划支持，研究含氧有机物的电化学氧化，使用实验和理论方法探索这些过程及其表现出的非线性行为。 大部分的努力将集中在甲酸氧化。 目的是表征阴离子影响氧化过程的不同方式，找到这些影响的起源，并研究这些影响是否可用于探测电化学机制。 通过研究阴离子与周围静止和瞬态邻居的相互作用，有望获得实质性的新认识。 研究成果有望提高对燃料电池应用中重要的氧化反应的理解。 这个项目将提供宝贵的介绍性研究机会，本科生在理论和实验化学。含氧有机化合物的电催化氧化由于其在燃料电池中的应用而具有重要意义。 许多学术和工业研究人员的目标是提高商业环境甲醇-空气燃料电池的可行性，以取代传统的化石燃料源。 这一目标很重要，因为环境中的温室气体正在增加，而且未来可能出现化石燃料能源短缺。 本研究的一个实际目标是通过类似于用于增强甲酸氧化的方法来增强甲醇氧化。 提高甲醇氧化转化为更有效的燃料电池。
