Atomic force microscopy study of anatase TiO₂(001)-(1 × 4) surface adsorved water molecule

Abstract

In previous STM studies, water molecules adsorb on the ridges of anatase TiO₂(001)-(1 × 4) surface at low-temperature and do not occur the adsorption at room temperature. In this study, we investigated whether or not water molecules adsorb on the anatase TiO₂(001)-(1 × 4) surface at room temperature by atomic force microscopy. Our results reveal that water molecules adsorb dissociatively on the ridge of (1 × 4) reconstructed surface at room temperature.
