Photocatalytic properties of titania powders prepared by hydrothermal method

Nanocrystalline titania with particle size ∼20–50nm and specific surface area ∼20–80m2g−1 is prepared by hydrothermal treatment of aqueous TiOSO4, H2TiO(C2O4)2, and TiO(NO3)2 solutions. The photocatalytic behavior of synthesized TiO2 powders is studied in the reaction of phenol photodegradation in w...

Description
Summary:Nanocrystalline titania with particle size ∼20–50nm and specific surface area ∼20–80m2g−1 is prepared by hydrothermal treatment of aqueous TiOSO4, H2TiO(C2O4)2, and TiO(NO3)2 solutions. The photocatalytic behavior of synthesized TiO2 powders is studied in the reaction of phenol photodegradation in water and optimal characteristics of these materials are explored. The best photocatalytic activity was observed for a mixture of rutile (15%) and anatase (85%) prepared by high-temperature hydrolysis of aqueous TiOSO4 solution.
