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Ag3PO4/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Ag3PO4/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%.
Abstract
Ag3PO4/AgBr composite nanomaterials and silver phosphate monomer were prepared by solvothermal method,with sodium phosphate,silver nitrate,polyethylene glycol and hexadecyl trimethyl ammonium bromide 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 de-termined.Using methylene blue dye as simulated pollutant,the degradation rate of methylene blue solution was in-vestigated by using Ag3PO4/AgBr composite nanomaterial as catalyst.The results showed that after 150 minutes un-der visible light,the degradation rate of methylene blue was 96.5%.
