摘　　要：以磷酸钠、硝酸银、聚乙二醇、十六烷基三甲基溴化铵等为原料,采用溶剂热法来制备Ag_(3) PO_(4)/AgBr复合纳米材料和磷酸银单体。利用X射线粉末衍射仪(XRD)、扫描电镜(SEM)等一些表征手段来确定所制备的材料的成分以及其结构形貌,进而确定较优的实验条件。以亚甲基蓝染料作为模拟污染物,探究Ag_(3) PO_(4)/AgBr复合纳米材料作为催化剂对亚甲基蓝溶液的降解率。实验结果显示,在可见光照射150 min后,亚甲基蓝的降解率为96.5%。Ag_(3)PO_(4)/AgBr composite nanomaterials and silver phosphate monomer were prepared by solvothermal method,with sodium phosphate,silver nitrate,hexadecyl trimethyl ammonium bromide and polyethylene glycol as raw materials.Using X-ray powder diffraction(XRD),scanning electron microscope(SEM)characterization methods such as to determine the composition and morphology of materials,and the optimal experimental conditions were determined.Using methylene blue dye as simulated pollutant,the degradation rate of methylene blue solution was investigated by using Ag_(3)PO_(4)/AgBr composite nanomaterial as catalyst.The results showed that after 150 minutes under visible light,the degradation rate of methylene blue was 96.5%.
