摘要:In the present work, the MoS2clusters/CdS (CMo/CdS) nanorod (NR) heterojunction photocatalysts were prepared through a simple one-pot solvothermal method under lower temperature. The cluster-structured MoS2is uniformly dispersed on the surface of CdS NRs, and the MoS2modification does not change the crystal structure and morphology of CdS NRs. The modification of MoS2can significantly enhance the photocatalytic hydrogen production performance of CdS NRs. When the molar ratio of MoS2to CdS NRs is 3%, the CMo/CdS NRs has the highest photocatalytic hydrogen evolution rate, 12.38 mmol·g−1·h−1, which is 17.4 times that of CdS NRs. The enhanced photocatalytic hydrogen production performance can be attributed to the co-catalytic action of MoS2, which can accelerate the photocatalytic hydrogen production process of CdS NRs. Meanwhile, MoS2can reduce the surface resistance of CdS NRs and improve the transmission of the photogenerated electrons to the surface of CdS NRs, resulting in the significant decrease of the recombination rate of the photogenerated electrons and holes, and thus promoting the photocatalytic hydrogen production performance of CdS NRs.
