The understanding of the electrochemical behavior of structurally characterized diamond thin films is the focus of this research project. With the support of the Analytical and Surface Chemistry Program, Professors John B. Cooper and Sacharia Albin and their coworkers at Old Dominion University are using CVD methods to grow diamond thin films. These films, characterized using scanning tunelling microscopy and other spectroscopic methods, are used to investigate the relationship between surface structure and inner and outer sphere electron transfer reactions. Chemical modification of the diamond surface is carried out using covalently bound molecular species, and the effect of this modification on the electrochemical behavior explored. Diamond thin films have promising applications in electrochemical and materials science systems. With the support of the Analytical and Surface Chemistry Program, Professors Cooper and Albin are exploring the connection between the structure of these films and their electrochemical properties. A series of probe reactions are being examined, for a range of carefully characterized diamond thin film materials. The information obtained from these studies will be very useful in developing improved and longer lasting electrocatalytic and sensor devices.

了解具有结构特征的金刚石薄膜的电化学行为是本研究项目的重点。 在分析和表面化学计划的支持下，教授约翰B。 库珀和萨查里亚阿尔宾和他们的同事在旧自治领大学正在使用化学气相沉积法生长金刚石薄膜。 这些薄膜，其特征在于使用扫描隧道显微镜和其他光谱方法，被用来调查表面结构和内部和外部球电子转移反应之间的关系。 利用共价键合的分子物种对金刚石表面进行化学改性，并探讨了这种改性对电化学行为的影响。 金刚石薄膜在电化学和材料科学系统中具有广阔的应用前景。 在分析和表面化学项目的支持下，库珀教授和阿尔宾教授正在探索这些薄膜的结构与其电化学性能之间的联系。 一系列的探针反应正在研究中，仔细表征的金刚石薄膜材料的范围。 从这些研究中获得的信息将是非常有用的，在开发改进的和更持久的电催化和传感器设备。
