摘　　要：采用两步水热法制备了BiSbO_(4)/BiOBr复合材料,并对其微观形貌、物相结构、化学组成、光学性能、光催化性能进行测试。结果表明:由纳米棒组成的BiSbO_(4)成功负载到片状BiOBr表面,二者产生的异质结结构不仅拓宽了催化剂的光响应范围还提升了光生电子-空穴对分离效率。其在模拟可见光下的光催化性能都优于单一的BiSbO_(4)和BiOBr,当BiSbO_(4)在复合材料中的质量分数为6%时,所制备的复合材料的光催化降解亚甲蓝(MB)性能最佳,其在模拟可见光下照射120min后对MB的降解率达91.3%,经过4次循环后降解率仍有77.4%。BiSbO_(4)/BiOBr composites were synthesized using a two-step hydrothermal method and thoroughly characterized in their microscopic morphology,physical phase structure,chemical composition,optical properties,and photocatalytic performance.The study revealed that nanorod-structured BiSbO_(4)was successfully deposited onto the surface of flaky BiOBr,forming a heterojunction that not only extended the photoresponsive range of the catalyst but also improved the separation efficiency of photogenerated electron-hole pairs.The photocatalytic activity under simulated visible light exceeded that of individual BiSbO_(4)and BiOBr.With a BiSbO_(4)mass fraction of 6%,the composite exhibited optimal photocatalytic degradation of methylene blue(MB),achieving a degradation rate of 91.3%after 120 min of irradiation.Furthermore,the degradation rate remained at 77.4%after four cycles.
