U.S.-Greece Cooperative Research: Nonfaradaic Electrochemical Modification of Catalyst Activity

9224854该奖项将支持耶鲁大学的加里·哈勒和希腊帕特拉斯大学的科斯塔斯·瓦耶纳斯之间的合作研究。这项合作将研究铂和钯催化剂上的非法拉第电化学修饰催化剂活性(NEMCA)。将研究三个反应：甲苯和苯的竞争加氢反应、甲醇氧化反应和新戊烷氢解反应。NEMCA效应将用扫描隧道显微镜和扩展的X射线吸收精细结构进行光谱研究。研究人员将寻求NEMCA效应的补充物理特征。催化反应将在两个实验室进行。STM工作将在帕特拉斯和耶鲁的EXAFS进行。在这两种情况下，光谱都将在现场进行，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。***

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. ***
