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.
