Provided are a MoSO/carbon nanocomposite material, a preparation method therefor and a use thereof. In the MoSO/carbon nanocomposite material, 2.5&#x2264;x&#x2264;3.1, 0.2&#x2264;y&#x2264;0.7, and the mass percent of MoSOis 5%-50% based on the total mass of the nanocomposite material. When the MoSO/carbon nanocomposite material is used as a catalyst for an electrocatalytic hydrogen evolution reaction, the current density is 150 mA/cmor more at an overpotential of 300 mV. The difference between this performance and the performance of a commercial 20% Pt/C catalyst is relatively small, or even equivalent; and this performance is far better than the catalytic performance of an existing MOScomposite material. The MoSO/carbon nanocomposite material also has a good catalytic stability, and after 8,000 catalytic cycles, the current density thereof is only decreased by 3%, thus exhibiting a very good catalytic performance and cycle stability.

MoSO/carbon nanocomposite material, preparation method therefor and use thereof

A MoS/carbon black nanocomposite material, and a manufacturing method and application thereof. In the MoS/carbon black nanocomposite material, 2&#x2264;x&#x2264;2.3. The weight percentage of MoSas part of the total weight of the nanocomposite material is 5-50%. The MoS/carbon black nanocomposite material has 20% higher performance when compared to a commercial 20% Pt/C catalyst. The manufactured MoS/carbon black nanocomposite material also has excellent catalytic stability. There is no significant decrease in catalytic performance of the material after 5,000 catalytic cycles.
