Dilute Sulfuric Acid

Aqueous suspensions of titanium dioxide (anatase) in dilute sulfuric acid solution containing ceric and thallous ions have been photolysed. The presence of TiO2 enhances the reduction rate by at least 40%. The observations are consistent with the formation of an additional yield of oxidizing radicals in the presence of the TiO2 which react with the same characteristics as the hydroxyl radical. The additional oxidizing radicals generated in the presence of TiO2 cannot be formed via hydrogen peroxide as an intermediate.
