초록

We present a nonprecious NiMo-based cathode with high activity and durability for proton exchange membrane water electrolysis, achieved via selective Zn dealloying and subsequent thermal annealing. This synergistic strategy simultaneously increases the electrochemically active surface area, achieving 1.897 A cm−2 at 2.0 Vcell, and ensures structural stability in acidic media.
