摘　　要：本文利用水热法合成了Ag3P04多面体微晶光催化剂，用X射线衍射仪（XRD）、场发射扫描电镜（FESEM）对所合成的样品进行了表征，实验结果表明利用水热法于140℃下反应6h制得的Ag3PO4样品为多面体微晶，反应温度、反应时间以及表面活性剂都对多面体微晶的结构与形貌造成影响。在可见光照射下，Ag3PO4多面体微晶样品对甲基橙和罗丹明B溶液有较好的光催化降解作用。ag3PO4 polyhedral microcrystals were prepared by hydrothermal method and characterized by XRD and FESEM. The results show that the Ag3 PO4 sample prepared by the hydrothermal method at 140 ℃ with 6h presents polyhed- ral morpphology with uniform sizes. The reaction temperature, process time and surfactants had great effects on the crystal structure and morphology of the microcrystals. Under visible light irradiation, the Ag3 PO4 polyhedral microcrystals prepared by the hydrothermal method showed perfect photocatalytic properties for the degradation of the methyl orange and Rhodamine B solutions.
