Oxide-supported Bimetallic Au-Pt Clusters as Catalysts for Epoxidation and Oxidation Reactions

美国国家科学基金会的分析和表面化学计划将支持南卡罗来纳大学的唐娜·陈教授的研究。陈教授和她的学生将开发新型二氧化钛负载的金-铂簇合物模型催化剂，用于丙烯直接转化为环氧丙烷。催化剂的结构和化学性质将用扫描隧道显微镜、低能离子散射和X射线光电子能谱在原子尺度上进行表征。与Monnier教授合作，陈教授和她的学生将建造一个催化反应器，以便在真实条件下研究丙烯氧化反应的机理和动力学。这项研究将为研究生和本科生提供表面科学和催化领域的培训机会。此外，陈教授还将参与南加州大学举办的旨在提高公众对纳米科学和纳米技术研究(包括纳米催化)的认识和理解的项目。

The Analytical and Surface Chemistry Program at the National Science Foundation will support the research of Professor Donna Chen of the University of South Carolina. Prof. Chen and her students will develop new Titania-supported gold-platinum cluster model catalysts for the direct conversion of propylene to propylene oxide. The structural and chemical properties of the catalysts will be characterized at the atomic scale using scanning tunneling microscopy and low energy ion scattering and X-ray photoelectron spectroscopies. In collaboration with Prof. Monnier, Prof. Chen and her students will construct a catalytic reactor to enable studying the mechanism and kinetics of the propylene oxidation reaction under real world conditions. The study will provide training opportunities to graduate and undergraduate students in the areas of surface science and catalysis. In addition, Prof. Chen will participate in USC run programs aiming to increase public awareness and understanding of nanoscience and nanotechnology research, including nanocatalysis.
