9224854 Haller This award will support collaborative research between Gary Haller, Yale University, and Costas Vayenas, University of Patras, Greece. The collaboration will investigate nonfaradaic electrochemical modification of catalyst activity (NEMCA) on Pt and Pd catalysts. Three reactions will be studied: competitive hydrogenation of toluene and benzene, methanol oxidation, and neopentane hydrogenolysis. The NEMCA effect will be investigated spectroscopically with scanning tunneling microscopy and extended X-ray absorption fine structure. The investigators will pursue complementary physical characterization of the NEMCA effect. The catalytic reactions will be carried out in both laboratories. The STM work will be performed in Patras and the EXAFS at Yale. In both cases, the spectroscopy will be performed in situ, and, to make these studies as complementary as possible, they will be perfomed using the same in situ reaction conditions. ***

9224854哈勒该奖项将支持耶鲁大学的加里·哈勒和希腊帕特雷大学的科斯塔斯·瓦耶纳斯之间的合作研究。该合作将研究Pt和Pd催化剂催化活性的非法拉第电化学修饰（NEMCA）。将研究三个反应：甲苯和苯的竞争性加氢、甲醇氧化和新戊烷的氢解。利用扫描隧道显微镜和扩展x射线吸收精细结构对NEMCA效应进行了光谱研究。研究人员将继续研究NEMCA效应的补充物理特性。催化反应将在两个实验室进行。STM的工作将在Patras和耶鲁大学的EXAFS进行。在这两种情况下，光谱学将在原位进行，并且，为了使这些研究尽可能互补，它们将使用相同的原位反应条件进行。＊＊＊
