The interplay between ambient water and reactive hydrocarbons on TiO2(110) was investigated using temperature programmed reaction and X-ray photoelectron spectroscopies. The ability of the surface to adsorb or dissociate water is dependent on the defect density and the presence of adsorbed species formed from hydrocarbon reaction. Recent studies are focusing on acrolein reactions. Synchrotron-based studies in the presence of water are also planned.
