The Interfacial Chemistry of Well-Defined Pd Electrodes: Studies by Surface Spectroscopy and Scanning Probe Microscopy

本研究项目由分析和表面化学项目支持，重点研究多晶和单晶钯电极的界面化学。Soriaga教授和他在德州农工大学的学生将使用电化学方法结合扫描隧道显微镜和表面光谱学来研究配位化学，溶液氧化还原对电子转移反应的吸附活化位点，以及钯电极表面发生的小分子电催化反应。涉及燃料电池、电催化、腐蚀/钝化和传感器的应用需要新的电极技术。许多这类应用程序的经济效益往往禁止它们在实际环境中被接受。钯电极表现出不寻常的现象，目前人们对这些现象知之甚少，但它们有可能在这些领域产生重大的科学和技术影响。为了更好地理解和控制这些不寻常的现象，将使用许多方法来研究钯电极表面在许多适合其在上述领域使用的条件下的性能。

This research project, supported by the Analytical and Surface Chemistry Program, focuses on the interfacial chemistry of polycrystalline and single-crystal palladium electrodes. Professor Soriaga and his students at Texas A & M University will use electrochemical methods combined with scanning tunneling microscopy and surface spectroscopy to study the coordination chemistry, adsorbate-activated sites for electron transfer reactions of solution redox couples, and electrocatalytic reactions of small molecules that occur at these palladium electrode surfaces. Applications involving fuel cells, electrocatalysis, corrosion/passivation, and sensors need new electrode technologies. The economics of many of these applications often prohibit their acceptance in real settings. Palladium electrodes exhibit unusual phenomena that are poorly understood at present but which have the potential to generate significant scientific and technological impact on these areas. A number of methods will be used to study the properties of palladium electrode surfaces under many conditions suitable for their use in the areas listed above in order to better understand and control these unusual phenomena.
