本研究项目在分析和表面化学计划的支持下，研究了步骤对铂单晶电极表面电催化和电沉积的影响。甲酸的电氧化和钴/铂磁性多层膜的沉积构成了康奈尔大学赫克托·D·阿布鲁纳教授进行的这项研究的主要重点。这项工作对电活性金属在燃料电池和磁性材料应用中的结构和功能之间的关系提供了详细的见解。详细了解电极表面结构与电极化学活性之间的关系是本研究项目的重点。利用表征良好的阶梯形单晶电极，正在研究有机小分子反应。此外，本工作还探索了将这些阶梯状表面用作磁性多层膜结构沉积的模板。这些研究的结果将为了解电催化系统的行为提供基本的见解。

This research project, supported by the Analytical and Surface Chemistry Program, addresses the effect of steps on electrocatalysis and electrodeposition on platinum single crystal electrode surfaces. The electrooxidation of formic acid, and the deposition of Co/Pt magnetic multilayers form the main focus of this research carried out by Professor Hector D. Abruna at Cornell University. This work provides detailed insight into the relation between structure and function of electroactive metals in fuel cell and magnetic material applications. The detailed understanding of the connection between electrode surface structure and electrode chemical activity is the focus of this research project. Using well-characterized stepped single crystal electrodes, small organic molecule reactions are being examined. In addition, the use of these stepped surfaces as templates for the structured deposition of magnetic multilayers is explored in this work. The results of these studies will provide fundamental insight into the behavior of electrocatalytic systems.
