One promising alternative for more efficient and sustainable energy storage systems is the utilization of Zn–O2 batteries, which boast higher densities compared with conventional Li-ion batteries. Despite their potential, batteries are not yet widely used in industrial applications due to low cyclability dependence on Platinum Group Metals (PGM). To address these issues, this research, development bifunctional electrocatalysts based Mn proposed. While documented like MnO2 demonstrate excellent catalytic behavior Oxygen Reduction Reaction (ORR), they lack Evolution (OER) capacity. In study, obtained through incorporation N (nitrogen) C (carbon) by using urea surfactants. The chemical, microstructural, electrochemical properties were thoroughly evaluated. results reveal that materials exhibit a capacity both ORR OER stable charge–discharge cycling performance reaching discharge 800 mAh g–1.
