Abstract
Provided are a MoSO/carbon nanocomposite material, a preparation method therefor and a use thereof. In the MoSO/carbon nanocomposite material, 2.5≤x≤3.1, 0.2≤y≤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.
