The Heterogeneous Oxidation of Sulfur Dioxide on Alkali Halide Surfaces: Kinetics and Mechanisms

该职业进步奖由分析和表面化学项目支持。Ganske教授将在加州大学欧文分校（University of California at Irvine）休假一年，与Hemminger和Finlayson-Pitts教授一起研究盐表面二氧化硫的非均相氧化化学。x射线光电子能谱和四极杆质谱将用于分析这些氧化反应的产物。这项工作将扩展Ganske教授在她自己的实验室中使用漫反射红外傅立叶变换光谱研究这些重要反应的经验。在她的休假结束后，一个新的四极杆质谱仪计划在佩珀代因大学的科学附件的新空间。这次休假将大大提高Ganske教授和她在佩珀代因大学的本科生在异质大气化学领域的未来研究经验。气态二氧化硫在无机表面的反应在许多由燃烧化石燃料引起的空气污染领域是重要的。在这项工作中，二氧化硫在无机表面的氧化将使用一些新的技术来表征佩珀代因大学的Ganske教授。这些经验将在加州大学欧文分校与Hemminger和Finlayson-Pitts教授一起休假期间获得。该项目的目的是开发以经济的方式有效地从气体样品中去除二氧化硫的工艺，并向本科生介绍这一重要的研究领域。

This Career Advancement Award is supported by the Analytical and Surface Chemistry Program. Professor Ganske will spend a sabbatical year at the University of California at Irvine working with Professors Hemminger and Finlayson-Pitts studying the heterogeneous oxidation chemistry of sulfur dioxide that occurs on salt surfaces. X-ray photoelectron spectroscopy and quadrupole mass spectrometry will be used to analyze the products of these oxidation reactions. This work will expand on the experience gained by Professor Ganske using diffuse reflectance infrared Fourier transform spectroscopy to study these important reactions in her own laboratory. Following her sabbatical leave a new quadrupole mass spectrometer is planned for new space in a science annex at Pepperdine University. This sabbatical will substantively enhance the future research experiences of Professor Ganske and her undergraduate students at Pepperdine University in the areas of heterogeneous atmospheric chemistry. The reactions of gaseous sulfur dioxide on inorganic surfaces is important in many areas of air pollution caused by the burning of fossil fuels. In this work the oxidation of sulfur dioxide on inorganic surfaces will be characterized using several techniques new to Professor Ganske of Pepperdine University. This experience will be gained during a sabbatical leave at the University of California at Irvine working with Professors Hemminger and Finlayson-Pitts. The aim of this project will be to develop processes that efficiently remove sulfur dioxide from gaseous samples in an economical way and to introduce undergraduate students to this important research area.
