• An apparent local surface structural change at nanoscale was observed by scanning tunneling microscopy on a TiO_2 surface upon irradiation with ultraviolet (UV) light. This phenomenon was reversible with UV light irradiation, and was interpreted to be due to the local accumulation of photoexcited states. This is the first real-space observation of inhomogeneous local charge distribution under UV light irradiation at nanoscale on a semiconductive photocatalyst surface, which may help identify the photocatalytic active sites and elucidate their reaction mechanisms.
