以Na2WO4·2H2O和Bi（NO3）3·5H2O为原料，采用机械球磨和煅烧两步法制备Bi2O3/Bi2WO6复合物。通过XRD和DRS对产物进行表征，研究制备条件（如球磨时间、煅烧时间）对复合物组成结构的影响。在可见光的照射下，以Bi2O3/Bi2WO6催化剂光催化降解罗丹明B溶液，结果表明，光照2 h后Bi2O3/Bi2WO6对罗丹明B的降解率达到98%。

Na2WO4·2H2O and Bi(NO3)3·5H2O are usedoas raw materials to prepare Bi2O3/Bi2WO6 composites by ball milling and subsequent thermal treatment. The composites are characterized by XRD and DRS,and the influence of the experimental parameters such as milling time,annealing time on the component and struc?ture of composites is studied. At the same time,the photocatalytic experimental results show that the prepared composite had good degradation activity for Rhodamine B under visible light irradiation,and the decoloriza?tion of Rhodamine B reaches as high as 98%after 2 h visible light irradiation.
