Unfortunately, the high overpotential of the oxygen evolution reactivity during recharge and the ineffective treatment thermodynamics of the oxygen reduction reaction during release seriously impedes the rapid advancement of Zn-air batteries. Cobalt-based electrode materials have recently piqued the interest of researchers due to their relatively high reliability and remarkable electrical and chemical functions, which stem from numerous electron setups and plentiful morphologies.
Furthermore, growing ZIFs on an encouraging material, such as electrospun nanofibers, can inhibit the aggregation of ZIF-based components and regulate their size, increasing their catalytic performance for different energy storage applications, such as Zn-air batteries. Key Developments of the Study The as-prepared blended catalysts for Zn-air batteries, composed of a specific quantity of Cr-doped nanostructured arrays on carbon nanofibers , perform exceptionally well in alkaline conditions. Moreover, the homogeneous 3D structure of the Cr-doped nanocomposites is credited for their flawless electrocatalytic consistency. The hybrid framework of catalysts greatly reduces active site agglomeration in Zn-air batteries.
