Heterostructures of CuS nanoparticle/ZnO nanorod arrays on carbon fibers with improved visible and solar light photocatalysis
CuS nanoparticle/ZnO nanorod heterostructure arrays grown on carbon fibers(CuS/ZnO/CFs)were prepared successfully by a simple combination of hydrothermal(HT)process and successive ionic layer adsorption and reaction(SILAR).The heterostructures of CuS/ZnO/CFs showed improved photocatalytic activity in the degradation of methylene blue(MB).Under visible light irradiation,the CuS/ZnO/CFs heterostructures exhibited remarkable visible light photocatalytic activity,which was 7.1 and 8.0 times higher than those of ZnO/CFs and ZnO,respectively.Under simulated solar light irradiation,the photocatalytic activity of the CuS/ZnO/CFs heterostructures was 1.4 and 2.2 times as high as those of ZnO/CFs and ZnO,respectively.The enhanced photocatalytic activity could be ascribed to the effective electron-hole separation and improved visible light utilization from the cooperative effect of the type Ⅱ CuS/ZnO heterostructures and conductive CFs,as well as the efficient light harvesting and high surface area of the heterostructure arrays.Moreover,the CuS/ZnO/CFs heterostructures can be easily separated and recycled with little loss in the photocatalytic activity due to their unique structural features.
