Titanium dioxide is a material material that has high catalytic action and has been studied extensively. However, the surface reactive process is not fully understood yet. In this research, we aimed to elucidate the reaction process of water molecules on the surface of rutile TiO ₂ (110) from the viewpoint of electronic state by X - ray photoelectron spectroscopy.We measured surface electronic state before and after exposing water by means of photoelectron spectroscopy.Furthermore, we examined the effects of X-ray irradiation.
