ABSTRACTProposal Title: Raman and Infrared Spectroscopic Characterization of Catalytic Interfaces in Flow Reactor and Gas-Phase EnvironmentsProposal Number: CTS-9813984Principal Investigator: Christos TakoudisInstitution: University of Illinois-ChicagoProfessor Christos Takoudis of U. Illinois at Chicago proposes to utilize surface-enhance Raman and infrared reflection absorption spectroscopies to analyze catalytic surfaces and intermediates under reaction conditions (up to 550 C). Simultaneously, reaction kinetic data will be obtained by means of mass spectrometric detection of gas phase species. The catalysts will be prepared by electrodeposition on roughened gold surfaces. Reactions to be studied include the decomposition and oxidation of alcohols and formic acid on Rh, Pt, Pd and Ir, and the oxidation of butadiene on Ag. An extensive range of temperature and pressures (up to 1 atm) will be utilized.

摘要提案标题：拉曼和红外光谱表征 流动反应器和气相环境中的催化界面提案编号： CTS-9813984主要研究者：Christine Takoudis机构： 伊利诺伊大学芝加哥分校教授。伊利诺斯州芝加哥提出利用表面增强拉曼和红外反射吸收光谱分析催化表面和反应条件下的中间体（高达550 ℃）。同时，通过气相物质的质谱检测获得反应动力学数据。催化剂将通过在粗糙的金表面上电沉积来制备。研究的反应包括醇和甲酸在Rh、Pt、Pd和Ir上的分解和氧化，以及丁二烯在Ag上的氧化。将使用广泛的温度和压力范围（高达1个大气压）。
