［Purposes］ The study aims at preparing MoS_x/Ti₃C₂T_x composites and study its catalytic performance for hydrogen evolution.［Methods］ MoS_x/Ti₃C₂T_x composites were prepared by wet chemical method using ammonium tetrathiomolybdate and Ti₃C₂T_x -MXene nanosheets as precursors. The MoS_x/Ti₃C₂T_x composites were characterized by X-ray photoelectron spectroscopy, X-ray diffraction, scanning electron microscopy and transmission electron microscopy. The hydrogen evolution catalytic properties of MoS_x/Ti₃C₂T_x composites were studied by electrochemical methods.［Findings］ The MoS_x in the composite was amorphous structure. MoS_x nanoparticles were uniformly dispersed on the surface of Ti₃C₂T_x nanosheets; The overpotential of MoS_x/Ti₃C₂T_x composite was only 207 mV at a current density of 10 mA/cm², and the Tafel slope was 46 mV/dec; After 1 000 cyclic voltammetry, the overpotential of the composite at 10 mA/cm² only increased with 7 mV; There was a strong interaction between the amorphous MoS_x and Ti₃C₂T_x, which significantly improved the conductivity of the amorphous MoS_x/Ti₃C₂T_x composite, it can increase the number of active sites which had exhibited excellent catalytic activity.［Conclusions］ MoS_x/Ti₃C₂T_x composites as electrocatalysts can be prepared by wet chemical method by using ammonium tetrathiomolybdate and Ti₃C₂T_x Mxene nanosheets as precursors. The composites have excellent catalytic activity and good cycle stability.
