Methanol is a promising hydrogen carrier for sustainable hydrogen production, but conventional electrocatalytic methanol oxidation for the hydrogen evolution reaction (HER) is limited by sluggish kinetics and susceptibility to catalyst poisoning. We developed a novel bifunctional Pt/Super-Electrically Activated Carbon (SEAC) catalyst coupled with a synergistic H3PMo12O40 (PMo12) and H4SiW12O40 (SiW12) system for hydrogen production from methanol. The integrated PMo12-SiW12 system can operate at a low voltage of 0.89 V to achieve 1 A cm-², reducing energy consumption to 1.73 kW·h Nm-³ H2, which is only 38.02% of that of conventional alkaline water electrolysis. This PMo12-SiW12 mediated approach can also be extended to other organic hydrogen carriers like ethanol, offering a low-cost, energy-efficient pathway for sustainable hydrogen production.
