Abstract: Zn2+ doped BiOBr (Zn/BiOBr) photocatalysts were prepared by solvothermal method,the structural and the photocatalytic performances of products were characterized by SEM,XRD,DRS,BET and the photo-degradation of rhodamine B (RhB).Experimental results showed that Zn/BiOBr were tetragonal phase,Zn/BiOBr samples had lower band gaps and higher specific surface area,which contributed to the higher photocatalytic performance.What is more,10% Zn/BiOBr samples revealed the most efficient for degradating RhB and the degradation rate were 96% within 120min under blue LED,which increased by 16% than that of pure BiOBr.After cycling for three times,the degradation rate of RhB maintained 85%.The results also suggested that h+ and ·O-2 were the main reactive species in the photocatalytic process for Rh B degradation.
