摘要
A novel Bi4Ti3O12/g-C3N4/BiOBr(BTO/CN/BOB) composite was synthesized by a solvothermal–mechanical mixed thermal method. The composition, structure, and micromorphology of the samples were analyzed. The BTO/CN/BOB composite photocatalyst shows better photocatalytic performance for tetracycline hydrochloride (TC) degradation compared to Bi4Ti3O12 and binary composite photocatalysts. The highest degradation rate of TC can reach 89.84% using the BTO/CN/BOB photocatalyst under the optimal conditions, and BTO/CN/BOB still exhibits good photocatalytic properties after recycling. Moreover, it also shows good photodegradation activity for different kinds of antibiotics, implying its wide application prospect. The photocatalytic performance and reuse stability of BTO/CN/BOB were significantly improved, which may be because of the enhanced spectral absorption range and efficient electron transfer capability by the synergistic effect and interaction among Bi4Ti3O12, BiOBr, and g-C3N4. Finally, the possible degradation pathway and electron transfer mechanism of the dual Z-scheme heterojunction are proposed.
