采用水热-光还原协同法成功制备了具有优良光催化性能的Ag/Bi 2 WO 6/石墨烯氧化物复合材料，并将其应用于抗生素的降解。采用傅立叶红外光谱（FTIR）、X射线光电子能谱（XPS）、比表面积分析仪（BET）、扫描电子显微镜（SEM）、X射线衍射（XRD）和原子力显微镜（AFM）等手段对催化剂的结构和性能进行了表征。结果表明，Ag和Bi 2 WO 6均匀负载在氧化石墨烯表面。此外，具有共轭碳网络结构的氧化石墨烯因其高电子电导率和大的反应活性中心而被用作光催化剂载体。与纯氧化石墨烯相比，所制备的Ag/Bi 2 WO 6/氧化石墨烯催化剂在紫外灯照射下对泰乐菌素具有良好的降解效率和稳定性。在模拟太阳光照射下，Ag/Bi 2 WO 6/石墨烯氧化物对泰乐菌素的光降解效率在2 h内达到98%，而纯石墨烯氧化物的光降解效率仅为50%。这种优异的光降解能力是由Ag、Bi 2 WO 6和氧化石墨烯纳米颗粒的协同作用引起的。
Ag/Bi2WO6/graphene oxide composite with excellent photocatalytic properties was successfully prepared by hydrothermal-photoreduction synergistic method and is applied in antibiotics degradation. The structure and properties of as-prepared photocatalysts were characterized by Fourier infrared spectrum (FTIR), X-ray photoelectron spectroscopy (XPS), specific surface area analyzer (BET), scanning electron microscopy (SEM), X-ray diffraction (XRD), and atomic force microscope (AFM). The results indicated that Ag and Bi2WO6were uniformly loaded on the surface of graphene oxide. In addition, graphene oxide with conjugated carbon network structures has been applied as a photocatalyst supporter for the high electronic conductivity and the large reactive sites. Compared with the pure graphene oxide, the as-prepared Ag/Bi2WO6/graphene oxide catalyst exhibited excellent degradation efficiency and stability for degrading tylosin under Xe lamp irradiation. Under simulated sunlight irradiation, the photodegradation efficiency of tylosin by Ag/Bi2WO6/graphene oxide achieved at 98% within 2 h, compared to 50% by pure graphene oxide. The excellent photodegradation ability is caused by the synergetic effect of Ag, Bi2WO6, and graphene oxide nanoparticles.
