摘　　要：采用沉淀法和浇铸成型法,制备聚偏二氟乙烯/磷酸银/炭黑(PVDF/Ag_(3)PO_(4)/CB)复合材料,通过傅里叶变换红外光谱(FTIR)、透射电子显微镜(TEM)、比表面积及孔径分析仪(BET)和紫外可见漫反射光谱仪(UV-Vis DRS)对复合材料的结构进行表征,并探究PVDF/Ag_(3)PO_(4)/CB对硝基苯的光催化降解性能。结果表明:Ag_(3)PO_(4)和CB材料能够较好结合,CB的填充未影响Ag_(3)PO_(4)的晶体结构。当Ag_(3)PO_(4)/CB的质量分数为3%,PVDF/Ag_(3)PO_(4)/CB光催化降解硝基苯的效率最高。40W紫外灯照射下,溶液初始质量浓度为40 mg/L,pH值为7时,尺寸为3 cm×3 cm的催化剂对溶液中硝基苯的降解率达到73.49%。Polyvinylidene method fluoride/silver phosphate/carbon The black(PVDF/Ag_(3)PO_(4)/CB)composites were prepared by precipitation spectroscopy and casting method.structure microscopy of the composites was characterized by pore fourier size transform analyzer infrared(BET)(FTIR),transmission electron(TEM),specific surface area and and ultraviolet-visible Ag_(3)PO_(4)/CB diffuse reflectance spectroscopy(UV-Vis DRS),and photocatalytic degradation be performance of PVDF/filling for nitrobenzene was explored.The results show that Ag_(3)PO_(4)and mass CB can well combined,3%,and the of the CB can not affect the crystal structure of Ag_(3)PO_(4).When the fraction of Ag_(3)PO_(4)/CB is PVDF/Ag_(3)PO_(4)/CB UV has highest mass photocatalytic degradation the efficiency is of nitrobenzene.and Under the the irradiation degradation of 40 rate W of lamp,when the the initial concentration of solution catalyst 40 mg/L the size.pH value is 7,nitrobenzene in solution reaches 73.49%with the of 3 cm×3 cm in size.
