Abstract: Provided is a high-efficiency vanadium nitride/molybdenum carbide heterojunction hydrogen production electrocatalyst, and a preparation method and application thereof. The electrocatalyst has a heterojunction structure formed by coupling VN and Mo2C, wherein the mass ratio of VN and Mo2C is 20:1 to 50:1. The electrocatalyst couples nano-VN and Mo2C to form a VN/Mo2C heterojunction, so that the active center is increased, and the balance of the reaction kinetics of H+ adsorption and H2 desorption is facilitated, thereby greatly improving the activity of the electrocatalyst.

Abstract: Provided is a three-phase system V2O3/VN/Mo2C nanoelectrode material, and a preparation method and application thereof. The nanoelectrode material comprises V2O3 particles, VN particles, and Mo2C particles. The V2O3 particles, VN particles, and Mo2C particles are interlaced in lattice stripes and are uniformly distributed. The mass ratio of the V2O3, VN and Mo2C is (1 to 4):(10 to 40):(4 to 16). The above-mentioned three kinds of nanoparticles are intertwined to form more incoherent interface area. The increase in the area of the incoherent interface area will cause more defects, so that more active sites are provided, and the hydrogen production performance is improved.
