We have performed density functional theory calculations to investigate SO2 adsorption on both ideal and defective TiO2(110) surfaces. In agreement with experiments, we identify SO2-, SO3- and SO4-like adsorption complexes. We also find that adsorption on the defective surface leads to very strong bonding between the molecule and the surface. More importantly, we show that upon adsorption on the defective surface the S hybridization changes from the sp(2) in the isolated molecule to the sp(3) type. We demonstrate that the change is responsible for the formation of stable SO4-like species at high temperature.
