Article Description

In this study, we report a novel carbon-based semiconductor photocatalyst g-CN/ZnWO nanocomposites with various contents of ZnWO were successfully constructed through a facile and eco-friendly in situ hydrothermal synthesis. The structure, morphology and chemical states of the as-prepared nanocomposites were studied by XRD, TEM and XPS measurements. Further, the surface of the fabricated 2D g-CN nanosheets was completely decorated with 1D ZnWO nanorods. The results of photocatalytic investigations signify that the synthesized heterostructured g-CN/ZnWO photocatalysts display substantially improved catalytic performance for the decolorization of rhodamine B (RhB) upon visible-light treatment. The improved catalytic activity could be attributed to the formation of heterojunction between g-CN and ZnWO, and effective photogenerated electron–hole pair’s separation. A likely catalytic reaction mechanism for the improved decomposition efficiency of RhB by g-CN/ZnWO nanocomposites is also proposed.
