Construction and performance of CdS/MoO2@Mo2C-MXene photocatalyst for H2 production
文献摘要：
Nowadays,photocatalytic technologies are regarded as promising strategies to solve energy problems,and various photocatalysts have been synthesized and explored.In this paper,a novel CdS/MoO2@Mo2C-MXene photocatalyst for H2 production was constructed by a two-step hydrothermal method,where MoO2@Mo2C-MXene acted as a binary co-catalyst.In the first hydrothermal step,MoO2 crystals with an egged shape grew on the surface of two-dimensional(2D)Mo2C MXene via an oxidation process in HCl aqueous solution.In the second hydrothermal step,CdS nanorods were uniformly assembled on the surface of MoO2@Mo2C-MXene in ethylenediamine with an inorganic cadmium source and organic sulfur source.The CdS/MoO2@Mo2C-MXene composite with MoO2@Mo2C-MXene of 5 wt％exhibits an ultrahigh visible-light photocatalytic H2 production activity of 22,672 μmol/(g·h),which is～21％higher than that of CdS/Mo2C-MXene.In the CdS/MoO2@Mo2C-MXene composite,the MoO2 with metallic nature separates CdS and Mo2C MXene,which acts as an electron-transport bridge between CdS and Mo2C MXene to accelerate the photoinduced electron transferring.Moreover,the energy band structure of CdS was changed by MoO2@Mo2C-MXene to suppress the recombination of photogenerated carriers.This novel compound delivers upgraded photocatalytic H2 evolution performance and a new pathway of preparing the low-cost photocatalyst to solve energy problems in the future.
