Inert Copper Incorporation Enables the High Activity and Durability of NiW Electrocatalyst for Alkaline Hydrogen Oxidation Reaction

Advanced Energy Materials, EarlyView.
Cu incorporation further refined the binding strength for intermediates (H* and OH*). Therefore, the resulting Cui‐NiW exhibited outstanding HOR activity, yielding a peak power density of 340 mW cm−2 in a noble metal‐free fuel cell. Moreover, the alloy demonstrated robust durability with only a 5.7% current drop after 10000 cycles.
