Abstract

An electrospun fiber with micro - nano - sized structure and carboxyl group was prepared by high - voltage electrospinning technology. In2S3-TiO2 particles were formed on the surface of the electrospun fibers by the hydrothermal method. The In2S3-TiO2 heterojunction/electrospinning fiber were characterized by SEM, XRD, XGA, TGA and UV-Vis. The In2S3-TiO2 heterojunctions can be evenly distributed on electrospun fibers. The photocatalytic hydrogen production performance of the composites was studied by using xenon lamp in the visible light source. Na2S / Na2SO3 was used as the sacrificial agent. The results show that the composite material has better photocatalytic hydrogen production capacity than the powder catalyst, and the average hydrogen production capacity is 15.29ml every two hours..
