Vanadium and Nitrogen were codoped in photocatalyst by Sol-gel method to utilize visible light more efficiently for photocatalytic reactions. A noticeable shift of absorption edge to visible light region was obtained for the singly-doped namely , and codoped samples in comparison with undoped , with smallest band gap obtained with codoped- . The photocatalytic activities for all photocatalysts were tested by 4-chlorophenol (organic pollutant) degradation under visible light irradiation. It was found that codoped exhibits the best photocatalytic activity, which could be attributed to the synergistic effect produced by V and N dopants.
