Innovative Air Cathode with Ni-Doped Cobalt Sulfide in Highly Ordered Macroporous Carbon Matrix for Rechargeable Zn-Air Battery.

ABSTRACT: To realize the practical application of rechargeable Zn-Air batteries (ZABs), it is imperative to develop a non-noble metal-based electrocatalyst with high electrochemical performance for the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER). Herein, Ni-doped Co₉S₈ nanoparticles dispersed on an inverse opal-structured N, S co-doped carbon matrix (IO─Ni_xCo_9-xS₈@NSC) as a bifunctional electrocatalyst is presented. The unique 3D porous structure, arranged in an inverse opal pattern, provides a large active surface area. Also, the conductive carbon substrate ensures the homogeneous dispersion of Ni_xCo_9-xS₈ nanocrystals, preventing aggregation and increasing the exposure of active sites. Th
