Abstract
Abstract The development of highly active and stable oxygen evolution reaction (OER) electrocatalysts is crucial for improving the efficiency of water splitting and metal–air battery devices. Herein, an efficient strategy is demonstrated for making the oxygen vacancies dominated cobalt–nickel sulfide interface porous nanowires (NiS 2 /CoS 2 –O NWs) for boosting OER catalysis through in situ electrochemical reaction of NiS 2 /CoS 2 interface NWs. Because of the abundant oxygen vacancies and interface porous nanowires structure, they can catalyze the OER efficiently with a low overpotential of 235 mV at j = 10 mA cm −2 and remarkable long‐term stability in 1.0 m KOH. The home‐made rechargeable portable Zn–air…
