摘要: The development of highly active and stable oxygen evolution reaction (OER) electrocatalysts is crucial for improving the efficiency water splitting metal-air battery devices. Herein, an efficient strategy demonstrated making vacancies dominated cobalt-nickel sulfide interface porous nanowires (NiS2 /CoS2 -O NWs) boosting OER catalysis through in situ electrochemical NiS2 NWs. Because abundant structure, they can catalyze efficiently with a low overpotential 235 mV at j = 10 mA cm-2 remarkable long-term stability 1.0 m KOH. home-made rechargeable portable Zn-air batteries by using NWs as air-cathode display very high open-circuit voltage 1.49 V, which maintain more than 30 h. Most importantly, self-driven device designed both anode cathode, powered two-series-connected NWs-based batteries. present work opens new way designing multifunctional reactions renewable energy
