We report the synthesis and visible light induced catalytic activity of brookite TiO2 nanocrystals. Brookite TiO2 nanostructure has been prepared by mechanical alloying the stoichiometric mixture of V2O5 and anatase TiO2 powders for 15h at room temperature in a planetary ball mill. The visible light driven photocatalytic activity have also been investigated with Rhodamine B dye molecules. The adsorption of the dye molecules on the photocatalyst surface have played a critical role in their selective photodegradation under visible light illumination.
