摘要
本文采用水热合成法合成表面具有大量绒毛分级结构蒲公英状Ag_3PO_4,并利用X射线衍射仪(XRD)、电子扫描显微镜(SEM)、紫外可见分光光度计等对其进行表征。实验结果表明,水热合成法制备的Ag_3PO_4与非水热合成的Ag_3PO_4颗粒在形貌上有明显不同。可见光下,在甲基橙(MO)光催化实验中,非水热合成法得到的Ag_3PO_4光催化效率明显低于蒲公英状Ag_3PO_4,这得益于蒲公英状Ag_3PO_4表面具有大量的光催化活性位点。蒲公英状Ag_3PO_410 min内对100 m L10 mg/L的甲基橙的降解效率是普通Ag_3PO_4颗粒的3.08倍。
In this paper,a novel photocatalytic dandelion-like Ag3PO4 was prepared by hydrothermal method,which surface full of a large number of villi hierarchical structures. The phase and shape of the photocatalytic was characterized by XRD,SEM,UV-vis. Results showed that the morphology of Ag3PO4 existed obviously different between hydrothermal and non-hydrothermal method. Meanwhile,under the condition of visible-light,the photocatalytic activity was tested by methyl orange（ MO 100 ml 10 mg / L）. Owning to the surface of dandelion-like Ag3PO4 had a lot of photocatalytic activity points,the photocatalytic degradation efficiency of dandelion-like Ag3PO4 to MO was 3. 08 times higher than normal Ag3PO4 particles in 10 min.
