| Abstract: 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 Bi0.96La0.04NbO4 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. |
