The control of pollutants has attracted considerable recent attention. The removal technology of antibiotics as pollutants becomes a challenge, especially water treatment technology based on photocatalytic degradation of antibiotics. In this paper, WO3 was prepared by a hydrothermal method, and the S-scheme heterojunction BiOBr/WO3 was constructed by a precipitation method at room temperature. Compared with BiOBr and WO3, the formation of S-scheme heterojunction improves the photocatalytic activity, and reduces the recombination rate of photogenerated electron-hole pairs. The optimum photocatalytic performance of BiOBr/WO3 with a mass fraction of 20% can be achieved, and the degradation rate for ciprofloxacin (CIP) is 94.93% within 120 min. Based on the electron spin resonance and radical trapping experiments, ·O2- is a primary active component in the photocatalytic degradation of CIP. The results of high-performance liquid chromatography-mass spectrometer system indicate that six intermediates are produced during the degradation of CIP, which are eventually mineralized into CO2, H2O and other inorganic ions.

国家高度重视新污染物治理，抗生素作为重点管控新污染物，其去除技术受到广泛关注，基于光催化降解抗生素的水处理技术成为研究热点。采用水热法制备了WO3，并采用室温沉淀法成功构建了S型异质结BiOBr/WO3光催化剂。与BiOBr和WO3相比，S型异质结的形成提高了光催化活性，降低了光生电子空穴对复合率，其中质量分数为20%的BiOBr/WO3复合材料光催化性能最好，在120 min内对环丙沙星的降解率可达94.93%。电子自旋共振和自由基捕获实验表明·O2-是光催化降解中的主要活性组分。高效液相色谱-质谱联用仪检测结果表明降解过程中产生了6种中间体，并最终矿化为CO2、H2O和其他无机离子。

国家高度重视新污染物治理，抗生素作为重点管控新污染物，其去除技术受到广泛关注，基于光催化降解抗生素的水处理技术成为研究热点。采用水热法制备了WO3，并采用室温沉淀法成功构建了S型异质结BiOBr/WO3光催化剂。与BiOBr和WO3相比，S型异质结的形成提高了光催化活性，降低了光生电子空穴对复合率，其中质量分数为20%的BiOBr/WO3复合材料光催化性能最好，在120 min内对环丙沙星的降解率可达94.93%。电子自旋共振和自由基捕获实验表明·O2-是光催化降解中的主要活性组分。高效液相色谱-质谱联用仪检测结果表明降解过程中产生了6种中间体，并最终矿化为CO2、H2O和其他无机离子。

The control of pollutants has attracted considerable recent attention. The removal technology of antibiotics as pollutants becomes a challenge, especially water treatment technology based on photocatalytic degradation of antibiotics. In this paper, WO3 was prepared by a hydrothermal method, and the S-scheme heterojunction BiOBr/WO3 was constructed by a precipitation method at room temperature. Compared with BiOBr and WO3, the formation of S-scheme heterojunction improves the photocatalytic activity, and reduces the recombination rate of photogenerated electron-hole pairs. The optimum photocatalytic performance of BiOBr/WO3 with a mass fraction of 20% can be achieved, and the degradation rate for ciprofloxacin (CIP) is 94.93% within 120 min. Based on the electron spin resonance and radical trapping experiments, ·O2- is a primary active component in the photocatalytic degradation of CIP. The results of high-performance liquid chromatography-mass spectrometer system indicate that six intermediates are produced during the degradation of CIP, which are eventually mineralized into CO2, H2O and other inorganic ions.
