Synthesis and visible light photocatalytic activity of transition metal oxide (V2O5) loading on TiO2 via a chemical vapor condensation method

► Increased BET value after vanadium impregnation. ► Enhanced OH radical on V2O5/CVC-TiO2. ► For the V2O5/CVC-TiO2, an absorption edge red shift was observed with an absorption tail extending to 600 nm.
