Surface Structure Effects on the Electrodeposition of Metal Monolayers

该研究项目由分析和表面化学项目支持，重点研究金属在单晶和金属表面上的欠电位沉积过程。康奈尔大学的Abruna教授和他的学生将使用动态电化学方法和x射线散射探针（如EXAFS和x射线表面衍射）的组合来研究这些过程。研究了沉积在铂电极上的银和铜的实时生长，并表征了卤化物和伪卤化物对吸附层结构的影响。这一信息对于理解电镀和薄膜生长的科学技术是至关重要的。研究在金属基底上电化学沉积金属薄膜的过程是本研究项目的重点。x射线和电化学方法将用于表征在沉积过程中形成的界面结构。这些信息有助于理解技术上重要的工艺，如电镀和缓蚀。

This research project, supported by the Analytical and Surface Chemistry Program, focuses on the development of an understanding of the process of underpotential deposition of metals on single crystal and deliberately stepped metal surfaces. Professor Abruna and his students at Cornell University will use a combination of dynamic electrochemical methods and X-ray scattering probes such as EXAFS and X-ray surface diffraction to study these processes. Real-time growth of silver and copper electrodeposited on platinum electrodes will be examined, and the effect on the structure of the adsorbed layer by halides and pseudo-halides will be characterized. This information is crucial to the understanding the science and technology of electroplating and thin film growth. Studies of the processes involved in the electrochemical deposition of thin metal films on metal substrates is the focus of this research project. X-ray and electrochemical methods will be used to characterize the interfacial structures as they are formed during the deposition process. This information is useful for understanding technologically important processes such as electroplating and corrosion inhibition.
