| 摘 要： | 以氧化石墨烯(GO)为基底，利用离子交换法制备了球形和立方体表面结构的Ag3PO4/GO复合光催化剂。通过X射线衍射(XRD)、扫描电子显微镜(SEM)和紫外-可见光谱(UV-Vis DRS)对样品进行了表征。罗丹明B的光催化降解实验结果表明：Ag3PO4/GO催化剂在100 min内对20 mg/L罗丹明B的去除率可达98.5%，明显高于球形Ag3PO4 (83.8%)及立方形Ag3PO4 (88.1%)。另外，Ag3PO4/GO复合材料在光催化降解重复性实验中表现出良好的稳定性，循环五次后对罗丹明B的去除率仍可达95%以上。

| Abstract: | Ag3PO4/GO photocatalysts with spherical and cubic surface structures were synthesized via ion exchange method using graphene oxide (GO) as a carrier. The properties of Ag3PO4/GO catalysts were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS). The capability of the catalysts was evaluated by rhodamine B (RhB) degradation experiments. The results showed that under the same conditions, 98.5% of RhB was removed by cubic Ag3PO4/GO in 100 min, which was significantly higher than that of pure spherical Ag3PO4 (83.8%) , cubic Ag3PO4 (88.1%). Moreover, the cubic Ag3PO4/GO catalysts exhibited perfect stability in photocatalytic degradation, and the removal rate of rhodamine B could still reach more than 95% after five reaction cycles. |
