Abstract Electrocatalytic hydrogen evolution reaction (HER) via alkaline water splitting holds great promise for industrial clean production but is frustrated by limited catalytic activity and inferior stability under high current density. Elaborate manipulating of heterostructure on robust electrodes essential challenging accelerating HER kinetics with durability. Herein, a nickel mesh electrode, offering mechanical stability, directly engineered layers multiple heterostructures (r‐Mn–Ni/CoP) facile one‐pot electrodeposition followed surface reconstruction strategy. The abundant composed crystalline CoP, NiP, amorphous region, additional Mn doping considerably manipulate the electronic structure optimized charge transfer; while in situ surface‐reconstructed hydrophilic nanoflakes enable rapid wetting active sites to electrolyte. Consequently, r‐Mn–Ni/CoP requires only 134 mV overpotential at density 100 mA cm −2 , superior monophasic undoped samples, majority reported catalysts. Remarkably, an electrolyzer cathode demonstrates extraordinary voltage 1.734 V 300 stable operation 800 h. finding provides feasible strategy fabrication nonprecious‐metal‐based electrocatalysts toward electrolysis.
