| 摘 要： | 采用醇辅助水热法,在固定醇与水体积比的情况下,加入乙醇、乙二醇、丙三醇成功制备了多形貌Ag_3PO_4光催化剂。使用扫描电子显微镜、X射线衍射仪、紫外-可见漫反射光谱等检测手段对样品的晶体形貌、晶相结构和光学性能进行表征。研究发现,反应体系中加入醇后,晶体的形貌、分散性及光电学性质发生改变,进而影响其光催化性质;可见光下降解Rh B实验显示,加入乙醇后制备的多面体Ag_3PO_4光催化降解能力最强。

| Abstract: | By fixing the volume ratio of alcohol and water,Ag3PO4 photocatalysts were synthesized by hydro-thermal route using ethanol,ethylene glycol,propanetriol respectively. The crystal morphologies,crystal structures and optical properties of Ag3PO4 polymorphs were characterized by scanning electron microscopy (SEM),X-ray diffraction (XRD),and ultraviolet-visible diffuse reflectance spectroscopy (UV-Vis DRS). The studies proved that the morphology,dispersion and optical properties of crystals were changed and the photo-catalytic properties were affected by the additions of alcohol. The experiment showed that polyhedral Ag3PO4 prepared by ethanol exhibited the highest photocatalytic activity in the photocatalytic degradation of RhB. |
