Abstract
Core-shell ZnO/BiOBr heterojunction was prepared by a simple hydrothermal-ionic liquid method. Hollow ZnO microspheres were firstly synthesized by hydrothermal method. Then BiOBr nanosheets were evenly wrapped on the ZnO microspheres through an ionic-liquid method. The prepared dahlia-like core-shell ZnO/BiOBr microspheres had a much larger BET surface area and mesopore volume than that of ZnO. Its visible-light absorption and charge carrier's separation were greatly enhanced due to the synergistic effect of the core-shell nanostructure and formation of ZnO/BiOBr heterojunction. It had an excellent photocatalytic performance in the degradation of tetracycline hydrochloride (TC): 86.76 % TC was degraded after irradiation for 90 min., which was 1.38 times of the pure ZnO and 1.35 times of the BiOBr, respectively.
