Developing effective electrocatalytic materials to enhance the hydrogen evolution reaction (HER) is essential for advancing hydrogen economy. In this study, molybdenum boride (MoB_x) electrocatalyst was successfully fabricated via the molten salt method, followed by Pt loading onto MoB_x using the impregnation-adsorption method. The introduction of Pt significantly boosted the electrocatalytic performance. The optimal Pt-MoB_x exhibited superior HER performance in 0.5 mol/L H₂SO₄, acquiring an overpotential of 49 mV at 10 mA/cm². Additionally, the Pt-MoB_x catalyst demonstrated exceptional stability in acidic medium, showing a negligible drop after 20 h of constant potential operation. The study presents a novel approach to design stable, high-efficiency HER electrocatalysts based on metal borides.
