Methanol-Enhanced Low-Cell-Voltage Hydrogen Generation at Industrial-Grade Current Density by Triadic Active Sites of Pt₁-Pd<i>_n</i>-(Ni,Co)(OH)_<i>x</i>.

ABSTRACT: Methanol (ME) is a liquid hydrogen carrier, ideal for on-site-on-demand H₂ generation, avoiding its costly and risky distribution issues, but this "ME-to-H₂" electric conversion suffers from high voltage (energy consumption) and competitive oxygen evolution reaction. Herein, we demonstrate that a synergistic cofunctional Pt₁Pd_n/(Ni,Co)(OH)_x catalyst with Pt single atoms (Pt₁) and Pd nanoclusters (Pd_n) anchored on OH-vacancy(V_OH)-rich (Ni,Co)(OH)_x nanoparticles create synergistic triadic active sites, allowing for methanol-enhanced low-voltage H₂ generation. For MOR, OH* is preferentially adsorbed on Pd_n and then interacts with the inter
