项目摘要

This research project, supported by the Analytical and Surface Chemistry Program, involves an experimental and theoretical study of the structure and properties of single crystal noble metal electrodes and gold electrodes modified by self-assembled monolayers. Professor Fawcett and his students at the University of California at Davis will use a variety of voltammetric methods and impedance spectroscopy to characterize these electrode surfaces immersed in various nonaqueous solvents. The distribution of potential over the double layer at these electrode/solution interfaces and the effect of solvent on this property will be determined. In concert with this experimental thrust theoretical work will be pursued to develop analytical expressions for these double layer properties that can be easily used by experimentalists. The double layer properties of single crystal noble metal electrodes and gold electrodes modified by self-assembled monolayers in various nonaqueous solvents will be studied experimentally and theoretically in this project. Professor Fawcett and his students at the University of California at Davis will use a variety of electrochemical methods and impedance spectroscopy in this work and analytical expressions that describe the double layer at these electrode/solution interfaces that can be easily used will be developed. The results from this work will be contribute to understanding the effects of solvent on the distribution of potential at these interfaces and this knowledge has relevance to a variety of `green` technologies.

该研究项目由分析和表面化学项目支持，涉及单晶贵金属电极和自组装单分子层修饰的金电极的结构和性能的实验和理论研究。加州大学戴维斯分校的 Fawcett 教授和他的学生将使用各种伏安法和阻抗谱来表征这些浸入各种非水溶剂中的电极表面。将确定这些电极/溶液界面处双层上的电势分布以及溶剂对此性质的影响。与该实验推力相一致，我们将开展理论工作，以开发这些双层特性的解析表达式，以便实验者可以轻松使用。本项目将对单晶贵金属电极和自组装单层修饰金电极在各种非水溶剂中的双层性能进行实验和理论研究。加州大学戴维斯分校的 Fawcett 教授和他的学生将在这项工作中使用各种电化学方法和阻抗谱，并且将开发描述这些电极/溶液界面双层的易于使用的分析表达式。这项工作的结果将有助于理解溶剂对这些界面电势分布的影响，并且这些知识与各种“绿色”技术相关。
