摘要

以氧化石墨烯(GO)为基底,利用共沉淀及离子交换两步法制备Ag3PO4/Fe3O4/GO 复合光催化剂.通过X射线衍射(XRD)、扫描电子显微镜(SEM)、透射电镜(TEM)、热重(TGA)、振动样品磁强计(VSM)及紫外-可见光谱(UV-Vis DRS, UV-4100,带积分球)对样品的特征基团、微观形貌及磁性质、光学性质等进行了鉴定和表征.光催化脱色实验结果表明:Ag3PO4/Fe3O4/GO 化剂20 min内对10 mg/L罗丹明B模拟水样的脱色率可达97.6%,高于Ag3PO4(73.4%);Ag3PO4/Fe3O4/GO 系中引入过硫酸钠可以起到强化光催化性能的作用;另外,Ag3PO4/Fe3O4/GO 剂表现出良好的活性稳定性、热稳定性及结构稳定性。

Abstract:

Ag3PO4/Fe3O4/GO composite photocatalysts were prepared via co precipitation and ion exchange method using graphene oxide (GO) as a carrier, which were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), thermogravimetry (TGA), vibrating sample magnetometer(VSM) and UV-Vis diffuse reflectance spectroscopy (UV-Vis DRS).The results of photocatalytic decolorization indicated that the Ag3PO4/Fe3O4/GO mposite photocatalysts showed better photocatalytic decolorization of Rhodamine B (97.6%) than that of pure Ag3PO4(73.4%) . The introduction of sodium persulfate into the Ag3PO4/Fe3O4/GO tocatalytic system could enhance the photocatalytic performance. In addition, Ag3PO4/Fe3O4/GO posite catalyst exhibited good activity stability, thermal stability and structural stability.
