Reactions of NOx, SO2, O3, and oxygenated hydrocarbons on oxide surfaces in high relative humidity are important in areas such as atmospheric chemistry and environmental catalysis. We are investigating the reactivity of metal oxides such as rutile TiO2 in the presence of water. We hope to gain further insight into the effect of OH and H2O on gas-oxide surface reaction rates, mechanisms, and products. Also, we are studying how these molecular interactions are affected by materials properties of the metal oxide such as terrace widths and defects. Our research involves reflection absorption infrared spectroscopy, temperature programmed reaction spectroscopy, low energy electron diffraction, and Auger electron spectroscopy.
