Molecular-level Studies of Surface Reactions

Understanding the surface reaction processes of ketones and aldehydes on metal oxide surfaces is important for photodegradation of toxic organic molecules. The consecutive reaction steps of acetone and formaldehyde molecules on rutile TiO2(110) surfaces have been studied using highresolution scanning tunneling microscopy (STM). Our studies have focused on how surface defects and co-adsorbates affect the chemical activity of the oxide. The unique methodology enabled us to follow key elemental steps (adsorption, dissociation, and diffusion) and identify various intermediates in heterogeneous catalytic reactions.
