摘要：

We have performed first-principles molecular dynamics calculations of water adsorption on TiO2 (110). We find that dissociative adsorption occurs at the fivefold-coordinated Ti site resulting in the formation of two types of hydroxyl group. The vibrational spectra calculated from this hydroxylated surface show that a clear stretch frequency is present for only one of these groups, with vibrations from the other hydroxyl broadened due to hydrogen bonding between the two hydroxyl groups.
