Developing cost-effective and high-performance non-precious metal-based electrocatalysts for hydrogen evolution reaction is of crucial importance toward sustainable energy systems. Herein, we prepare a novel hybrid electrode featuring intermetallic Fe2Mo nanoparticles anchored on the hierarchical nanoporous copper skeleton as robust electrocatalyst by simple scalable alloying dealloying methods. By virtue highly active unique bicontinuous facilitating ion/molecule transportation, Fe2Mo/Cu shows excellent electrocatalysis, with low Tafel slope (~71 mV dec−1) to realize ampere-level current density 1 A cm−2 at overpotential ~200 in M KOH electrolyte. Furthermore, exhibits long−term stability exceeding 400 h maintain ~250 mA an 150 mV. Such outstanding electrocatalytic performance enables be attractive catalyst water splitting economy.
