Water-Mediated Chemistry of Metal Oxides

该项目由分析和表面化学计划支持，研究了吸附水对矿物氧化物表面上NOx、SO2、O3和含氧有机物的吸附和反应的影响。 使用反射-吸收红外，高压XPS和质谱法的组合，以监测表面反应化学，沿着与扫描探针显微镜的氧化物表面的表征，有关这种表面化学的基本信息正在获得。 弗伦德教授和她在哈佛大学化学系的同事正在研究这些与环境相关的表面化学反应。 对研究生、本科生和博士后的培训有助于这项工作产生更广泛的影响。 吸附水如何影响氧化物表面小分子的反应化学是本研究项目的主题。 在分析和表面化学计划的支持下，Friend教授和她的同事正在获得有关这些对环境重要的表面反应机制的分子水平信息。 这项工作的更广泛影响包括与大气化学和多相催化有关的信息，以及对下一代学生的培训。

AbstractCHE-0545335Friend/HarvardThis project, supported by the Analytical and Surface Chemistry Program, addresses the effect of adsorbed water on the adsorption and reaction of NOx, SO2, O3 and oxygenated organics on mineral oxide surfaces. Using a combination of reflection-absorption infrared, high pressure XPS, and mass spectrometry to monitor the surface reaction chemistry, along with scanning probe microscopy for the characterization of the oxide surface, fundamental information about this surface chemistry is being obtained. Professor Friend and her coworkers in the Department of Chemistry at Harvard University are examining these environmentally relevant surface chemical reactions. Training of graduate students, undergraduates, and postdoctoral associates contribute to the broader impacts of this work. How adsorbed water affects the reaction chemistry of small molecules on oxide surfaces is the subject of this research project. With the support of the Analytical and Surface Chemistry Program, Professor Friend and her coworkers are obtaining molecular level information about the mechanisms of these environmentally important surface reactions. The broader impacts of this work include information relevant to atmospheric chemistry and heterogeneous catalysis, as well as the training of the next generation of students.
