Efficient charge carrier transfer route induced by Z-scheme CdS/BiOBr heterostructure for enhanced photocatalytic performance

Z-scheme CdS/BiOBr heterostructure was synthesized by hydrothermal method and demonstrated an enhanced photocatalytic performance in degrading Ciprofloxacin (CIP) of 90% within 120 min under visible light irradiation. Meanwhile, the degradation of Rhodamine B (RhB) and Tetracycline (TC) are tested when we explored the optimal synthesis time of BiOBr and proportion of heterostructure. The enhancement of photocatalytic performance can be attributed to the extended visible light absorption as well as the Z-scheme photo-generated carriers’ transfer route.
