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.

该研究项目得到了分析和表面化学计划的支持，涉及对由自组装单层修饰的单晶贵金属电极和金电极的结构和特性进行的实验和理论研究。 Fawcett教授及其学生在加利福尼亚大学戴维斯分校的学生将使用各种伏安方法和阻抗光谱来表征这些电极表面，这些电极表面沉浸在各种非水溶剂中。将确定在这些电极/溶液界面上双层上电势的分布，并确定溶剂对该特性的影响。将与实验推力理论工作一致，以开发这些双层特性的分析表达式，这些特性很容易被实验者使用。在该项目中，将对各种非水溶剂中的自组装单层修饰的单晶贵金属电极和金电极的双层特性进行了研究。 Fawcett教授及其在加利福尼亚大学戴维斯分校的学生将在这项工作和分析表达式中使用各种电化学方法和阻抗光谱，这些方法描述了这些电极/溶液界面处的双层层，将开发。这项工作的结果将有助于理解溶剂对这些接口处电势分布的影响，并且这些知识与各种“绿色”技术相关。
