The molten salt electrolysis method and transition metal Cu-doping were used to prepare two different of nanostructured Cu/MoS₂. Two kinds of Cu/MoS₂ working electrodes were prepared by coating method. X-ray diffraction, transmission electron microscope, energy dispersive X-ray spectroscopy, scanning electron microscope, selected area electron diffraction and various electrochemical methods were used to study the structure and performance. The results showed that Cu/MoS₂ nanosheets exhibited excellent hydrogen evolution reaction catalytic performance in alkaline solution (1 mol·L^-1 KOH): when the current density was 10 mA·cm^-2, the overpotential was 199.6 mV, and the Tafel slope was 59 mV·dec^-1, double layer capacitor was 26.1 mF·cm^-2, equivalent charge transfer resistance was 12.4 Ω, and showed relatively good electrochemical durability and stability.
