TiO2 deactivation is studied during the gas-phase photocatalytic oxidation of organics containing three different heteroatoms: Si, N and S. Auger electron spectroscopy is used to characterize the catalyst poisoning species. A kinetic equation is presented which account for the activity vs. time observed data. Finally, an estimation is made of the equivalent monolayers of reactant converted prior total activity disappearance.
