It is challenging yet highly desirable to explore high-performance inexpensive electrocatalysts toward advanced zinc-air batteries (ZABs). Herein, a bifunctional oxygen electrocatalyst composed of Co9S8 incorporated into N-doped porous cross-linked carbon nanotubes (denoted as Co9S8–NC/NTs) reported through folic acid-assisted hydrothermal, pyrolysis, and sulfurization process. Owing the synergistic effect nanoparticles (NPs), Co–Nx active sites, three-dimensional (3D) network, Co9S8–NC/NTs show enhanced activity small potential gap 0.72 V. Moreover, ZAB assembled with serving cathode exhibits satisfactory long-term durability up 140 h (840 cycles) large power density 116.6 mW cm–2. The present study offers an effective strategy for constructing catalysts based on multielements-functionalized rechargeable ZABs.
