项目摘要
ABSTRACT CTS-9610140 Professor Victor E. Henrich of Yale University is being funded by the Kinetics and Catalysis-CRP-CTS and the Solid State Chemistry-DMR programs. He will investigate the contribution of delocalized electronic states to chemisorption on transition-metal-doped oxides, taking as model Cr-doped V203 single crystal. The electronic structure of the model catalytic oxide will be varied independently from the structure over a wide range of doping with Cr. The surface electronic structure will also be controlled by taking advantage of the hysteresis of the metal-insulator transition with temperature. The system will be studied with UHV techniques (UPS, XPS, LEEDS, HREELS, Auger, inverse photoelectric techniques) and by chemisorption and TPD of probe molecules such as CO, H20, O2, and NO. This work is of relevance to fundamental chemisorption and catalysis, surface science, and materials science.
摘要 CTS-9610140 耶鲁大学 Victor E. Henrich 教授获得了动力学和催化-CRP-CTS 以及固态化学-DMR 项目的资助。他将以 Cr 掺杂 V2O3 单晶为模型,研究离域电子态对过渡金属掺杂氧化物化学吸附的贡献。 模型催化氧化物的电子结构将独立于大范围的 Cr 掺杂的结构而变化。 表面电子结构也将通过利用金属-绝缘体转变随温度的滞后来控制。 该系统将通过 UHV 技术(UPS、XPS、LEEDS、HREELS、Auger、逆光电技术)以及 CO、H2O、O2 和 NO 等探针分子的化学吸附和 TPD 进行研究。这项工作与基础化学吸附和催化、表面科学和材料科学相关。
