摘要：

In the context of energy crisis, the use of MoS2 for photocatalytic water splitting to produce hydrogen is very attractive. The narrow light absorption range and rapid carrier recombination are the key issues limiting the photocatalytic performance of MoS2. The heterostructure CdS/MoS2/CNFs composite catalyst was prepared by electrospinning, high-temperature calcination and solvothermal method. The composite exhibits excellent photocatalytic performance under visible light irradiation (lambda > 420 nm), and 1.0-CMC exhibits an optimal hydrogen evolution rate of 3195.52 mu molg(-1)h(- 1), which is 17 times that of pure MoS2. The results demonstrate that the enhanced photocatalytic performance is attributed to the joint effect of the heterojunction structure and flake MoS2. (1) The compact heterojunction structure is formed between CdS and MoS2, which greatly improves the transfer rate of photogenerated carriers. (2) The flake MoS2 provides abundant active sites and promotes the hydrogen evolution reaction. This work prepared a new type of nano-photocatalytic material, which has great potential in the application of photocatalytic hydrogen production.
