摘要
ZnO-CC and ZnO/Bi2WO6-CC with different Bi2WO6 loadings layered heterostructures photocatalysts were synthesized on flexible carbon clothes (CC) substrate by the thermal decomposition-hydrothermal method. By characterizing the degradation of methylene blue (MB) under ultraviolet light irradiation, Z3B-CC (3 wt% Bi2WO6) showed the best photocatalytic effect, and the photodegradation rate of MB was as high as 96.9% in about 100 min. This new ZnO/Bi2WO6-CC layered heterostructure exhibits prominent photocatalytic performance, which is mainly ascribed to the type II band structure formed by ZnO andBi(2)WO(6). The appropriate energy band position further facilities the effective transfer of carriers and realizes the photocatalytic process of the heterostructure. This study is prospective to provide new ideas for the synthesis of other high-efficiency heterostructure photocatalytic designs, and it also has reference value for the synthesis of flexible photo catalytic materials with excellent performance.
