Although step structures have generally been considered to be active sites, their role on a TiO<sub>2</sub> surface in catalytic reactions is poorly understood. In this study, we measured the contact potential difference around the steps on a rutile TiO<sub>2</sub>(110)-(1 × 1) surface with O<sub>2</sub> exposure using Kelvin probe force microscopy. A drop in contact potential difference was observed at the steps, indicating that the work function locally decreased. Moreover, for the first time, ...[more]
