Promoting the rate of oxygen reduction reaction (ORR) is critical for boosting overall energy efficiency flexible zinc–air batteries (FZABs). Inspired by nature, we designed "branch-leaf" like hierarchical porous carbon nanofibers with ultralow loadings Ir nanoparticles (NPs) derived from covalent–organic framework/metal–organic framework (COF/MOF) core–shell hybrids. The as-obtained Ir/FeZn-hierarchical (HPCNFs) showcase enhanced ORR performance, and loading reduces cost while maintaining catalytic capacity. Interestingly, FZABs assembled Ir/FeZn-HPCNFs deliver an impressive stable performance. This work provides a feasible approach designing cost-effective highly efficient electrocatalysts using in FZABs.
