摘　　要：将g-C_(3)N_(4)和Bi_(2)WO_(6)制备复合材料g-C_(3)N_(4)@Bi_(2)WO_(6),通过SEM、XRD以及PL等技术对g-C_(3)N_(4)@Bi_(2)WO_(6)进行了结构和光学性质的表征,并以罗丹明B(RhB)为目标染料,考察了不同负载量的催化性能差异,推测其光催化机理.实验证明复合材料稳定性很好,并且催化性能相对于纯的g-C_(3)N_(4)和Bi_(2)WO_(6)有了很大的提高.这项工作为高活性异质结构光催化剂的设计和合成提供了思路.The g-C_(3)N_(4)and Bi_(2)WO_(6)were used to prepare the composite g-C_(3)N_(4)@Bi_(2)WO_(6).The structural and optical properties of g-C_(3)N_(4)@Bi_(2)WO_(6)were characterized by SEM,XRD and PL techniques.Taking rhodamine B(RhB)as the target dye,the difference in catalytic performance with different loading amounts was investigated,and the photocatalytic mechanism was speculated.It was demonstrated that the composites were very stable and the catalytic performance was greatly improved relative to pure g-C_(3)N_(4)and Bi_(2)WO_(6).This work provides ideas for the design and synthesis of photocatalysts with highly active heterostructures.
