A Direct View at Atomic Scale=0D=0A=
The catalytic activity of reducible oxides is often dominated by surface defects. Our studies have focused on how such reactive sites affect the=0D=0A=
chemical activity of the oxide, specifically TiO2, using scanning tunneling microscopy (STM). Acetone and formaldehyde on rutile TiO2(110) surface represent important model systems used to study oxidation of organic contaminants. The unique methodology enabled us to achieve the atomiclevel understanding of the key elemental steps — adsorption, dissociation, and diffusion — taking place in heterogeneous catalytic=0D=0A=
