Highlights The 2D CoOOH sheet-encapsulated Ni 2 P into tubular arrays electrocatalytic system with expediting mass transport, structural stability, and tuned electron was conceptually proposed. The designed electrocatalysts realize expectant 1000 mA cm −2 -level-current-density hydrogen evolution in...
