Abstract

This paper focuses on the preparation of ZnS/conducting polymer fiber composites and their performance for hydrogen evolution from splitting of water via photocatalytic reaction . The nano graphite as electrically conductive fillers were added into polyvinylidene fluoride (PVDF) and styrene maleic anhydride copolymer (SMA) solution s, which was electrospun to make the electrically conductive polymer fibers . ZnS particles were uniformly formed on the surface of conductive polymer fibers by hydrothermal method. The rising rate of H 2 generation of ZnS/conductive polymer fiber composites was quicker than that of ZnS/no n conductive polymer fiber composites. In the third run, the average rate of H 2 evolution of ZnS/conductive polymer fiber composites was 1.35 times that of ZnS/non conductive polymer fiber composites and 1.95 times that of ZnS powders. The electrical condu ctivity of carriers had an obvious effect on enhancing the photocatalytic efficiency of ZnS..
