Nitrogen-doped graphitic carbon materials hosting single-atom iron (Fe-N-C) are major non-precious metal catalysts for the oxygen reduction reaction (ORR). The nitrogen-coordinated Fe sites described as first coordination sphere. As opposed to good performance in ORR, that evolution (OER) is extremely poor due sluggish O-O coupling process, thus hampering practical applications of rechargeable zinc (Zn)-air batteries. Herein, we succeed boosting OER activity Fe-N-C by additionally incorporating phosphorus atoms into second sphere, here denoted P/Fe-N-C. resulting material exhibits excellent 0.1 M KOH with an overpotential low 304 mV at a current density 10 mA cm-2.

The detrimental parasitic reactions and uncontrolled deposition behavior derived from inherently unstable interface have largely impeded the practical application of aqueous zinc batteries. So far, tremendous efforts been devoted to tailoring interfaces, while stabilization grain boundaries has received less attention. Here, we demonstrate that preferential distribution intermetallic compounds at via an alloying strategy can substantially suppress intergranular corrosion. In-depth morphology analysis reveals their thermodynamic stability, ensuring sustainable potency. Furthermore, hybrid nucleation growth mode resulting reduced Gibbs free energy contributes spatially uniform Zn nuclei, promoting dense deposition. These integrated merits enable a high reversibility 99.85% for over 4000 cycles, steady charge-discharge 10 mA cm-2, impressive cyclability roughly 3500 cycles in Zn-Ti//NH4V4O10 full cell.
