Environmental photochemistry: Is iron oxide (hematite) an active photocatalyst? A comparative study: α-Fe_2O_3, ZnO, TiO_2
Chicago
Abstract
The photocatalytic activity of α-Fe2_O_3 colloids is compared to the activities of colloids and suspensions of ZnO and TiO_2. The formation of H_2O_2 is investigated and the oxidation of organic molecules is studied with high sensitivity. While ZnO and TiO_2 are found to be quite active photocatalysts in the formation of hydrogen peroxide and in the degradation of chlorinated hydrocarbon molecules, only negligible photocatalytic activity is found for α-Fe_2O_3. Upper limits of quantum yields for several photoreactions of α-Fe_2O_3 are given.
