Niobate bismuth nanoparticles doped with La and Zn had been prepared by chemical co-precipitation method, and its structure and photocatalytic property were characterized by means of modern analytical techniques.The results illustrated that the doped BiNbO₄ samples presented an excellent photocatalytic activity on RhB in visible light irradiation, and their photocatalytic efficiency influenced by various factors, 0.15 g of Bi_0.96La_0.04NbO₄ had the best photocatalytic effect on 50 mL of RhB solution with 5 mg·L^-1 and 4 of pH.Especially, it had a stable photocatalytic performance and still retained the photocatalytic activity beyond 95% after five cycling test.The study on photocatalysis mechanism indicated that the electron holes play a significant role in the degradation process of RhB under visible light irradiation.
