• TiO<SUB>2</SUB>(anatase) doped with various elements was used as the photocatalyst in the production of sulfuric acid from sulfur in water into which O<SUB>2</SUB> was bubbled. The catalysts doped with typical elements having one and two valencies showed high catalytic activity, but some doped with typical elements having four and five valencies showed low activity. The intermediate, <I>i.e.</I>, \dotO<SUB>2</SUB>H radical, in the O<SUB>2</SUB> reduction produced by photoproduced electrons will probably play an important part in the production of sulfuric acid. Therefore, it was suggested that the Ti<SUP>3+</SUP> ion in the TiO<SUB>2</SUB> lattice which contribute to direct O<SUB>2</SUB> reduction will inhibit sulfuric acid production. In the case of transition metal dopants, the transition metal cation in the TiO<SUB>2</SUB> lattice will directly affect the O<SUB>2</SUB> reduction. The catalyst doped (deposited) with Pt shows the highest catalytic activity of all the catalysts used in the present study.
