Analytical and Mechanistic Studies in Electrochemistry

丹尼斯·埃文斯教授和他的研究小组将研究双电子转移反应，重点关注与第二电子转移步骤相关的现象。涉及协同电子和质子转移（CEPT）的反应将特别有趣。对CEPT机制的要求，包括动力学障碍和反应物和产物的酸碱性质将进行研究。通过其在腐蚀和燃料电池功能中的作用，与生命过程和技术重要性密切相关的双氧还原将是选择进行详细研究的系统之一。涉及电位反转的反应，即在双电子过程中第二个电子的插入或移除比第一个电子的移除更容易发生的现象，也将作为项目主要推进的一部分进行研究。有关的应用工作也正在进行，包括电化学生成碱作为碱催化合成反应的试剂。本研究将发展对多电子转移反应的基本认识。将采用现代电化学方法。成果将与广泛的领域高度相关。影响生物系统、能源生产和高价值化学品合成的过程就是几个例子。

Professor Dennis Evans and his research group will investigate two-electron transfer reactions focusing on phenomena associated with the second electron transfer step. Reactions that involve concerted electron and proton transfer (CEPT) will be of special interest. Requirements for the CEPT mechanism including kinetic barriers and the acid-base properties of reactants and products will be investigated. Dioxygen reduction, which has great relevance to life processes and technological importance through its role in corrosion and fuel cell function, will be among the systems selected for detailed study. Reactions that involve potential inversion, the phenomenon where the insertion or removal of the second electron in a two electron process occurs more easily than does removal of the first electron, will also be studied as part of the major thrust of the project. Related applied work involving electrochemical generation of bases for use as reagents in base-catalyzed synthetic reactions is also being undertaken. This research will develop fundamental understanding of multi-electron-transfer reactions. Modern electrochemical methodology will be employed. Outcomes will be highly relevant to a wide range of areas. Processes that affect biological systems, energy production, and synthesis of high value chemicals are a few examples.
