| 摘要: 通过熔盐电解法并掺杂过渡金属Cu制备2种不同纳米结构的Cu/MoS2。采用涂敷法制备工作电极，通过X射线衍射（XRD）、透射电子显微镜（TEM）、能量散射X射线谱（EDS）、扫描电子显微镜（SEM）、选区电子衍射（SAED）以及各种电化学手段验证了其结构和性能。结果表明，纳米片状Cu/MoS2在碱性溶液（1 mol·L-1 KOH）中表现出优异的析氢催化性能：在电流密度为10 mA·cm-2时过电位为199.6 mV，Tafel斜率为59 mV·dec-1，双电层电容为26.1 mF·cm-2，等效电荷转移电阻为12.4 Ω，具有较为良好的电化学耐久性和稳定性。 | |

| Abstract: 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. | |
