摘　　要：本文采用一种简单、温和的光化学方法制备了约克球状ZnWO4/Ag复合材料。采用XRD、UV-vis DRS、SEM和TEM等对产物的纯度和微观结构进行了表征。在氙灯照射下,以甲基蓝(MB)为目标染料,探究了ZnWO4/Ag的光催化活性。与单一约克球状ZnWO4相比,约克球状ZnWO4/Ag复合材料在可见光辐照下对MB的光催化降解性能明显提高。其独特的中空结构和优异的性能赋予了约克球状ZnWO4/Ag在可见光催化领域广阔的应用前景。In this work, a simple and mild photochemical method was explored to synthesize yolk-shell spherical ZnWO4/Ag composites. The purity and microstructures of the products were measured by XRD, UV-vis DRS, SEM, TEM and EDXA. Methyl blue (MB) was adopted as target organic dye to investigate the photocatalytic activity of ZnWO4/Ag under xenon lamp irradiation. Compared with pristine ZnWO4 yolk-shell microspheres, the visible-light photocatalytic performance of ZnWO4/Ag microspheres was significantly improved. The unique hollow structures together with their excellent properties might endow ZnWO4/Ag yolk-shell microspheres with broad application prospects in catalysis field.
