Degradation of rhodamine B by Bi2O3/BiOCl heterojunction photocatalyst.

A new Bi2O3/BiOCl heterojunction photocatalyst characterized by XRD and SEM was prepared by mechanical grinding.The photocatalytic properties of the photocatalyst for the degradation of rhodamine B were investigated.The results show that the ratio of Bi2O3 and BiOCl has significant effect on the photocatalytic effect,and the photocatalytic activity of the Bi2O3/BiOCl was better than that of Bi2O3,BiOCl and commercial TiO2.
