Vertically Arrayed Co 4 N/MoN Nanosheets for Robust Alkaline Electrocatalytic Hydrogen Evolution at Ampere‐Level Current Density

Metal nitride electrocatalysts have been extensively developed for efficient alkaline water splitting, but it still remains a huge challenge in improving their stability especially at high current density of over 500 mA cm−2. Herein the Co4N/MoN electrocatalyst with hierarchical nanoparticle‐asse…
