Transition-metal carbides have been advocated as the promising alternatives to noble-metal platinum-based catalysts in electrocatalytic hydrogen evolution reaction over half a century. However, effectiveness of transition-metal catalyzing high-pH electrolyte is severely compromised due lowered proton activity and intractable alkaline-leaching issue centers. Herein, on basis validation molybdenum-carbide model-catalyst system by taking advantage surface science techniques, Mo2C micro-size spheres terminated Al3+ doped MoO2 layer exhibit notable performance alkaline with near-zero onset-potential, low overpotential (40 mV) at typical current density 10 mA/cm2, small Tafel slope (45 mV/dec), well long-term stability for continuous production 200 h. Advanced morphology spectroscopy characterizations demonstrate that local -Al-OH-Mo- structures within Al-MoO2 terminations serve strong Brønsted acid sites accelerate deprotonation kinetics HER process. Our work paves an interesting termination-acidity-tailoring strategy explore cost-effective towards water electrolysis beyond. Exploring low-cost, efficient replace platinum crucial generation.
