The rechargeable Zn-nitrate battery presents a promising strategy for renewable energy conversion, ammonia production, and sewage treatment. Despite achieving excellent performance with transition metal-based electrocatalysts, the structure evolution of electrocatalyst during charging/discharging corresponding reaction mechanism on nitrate reduction (NO3RR) are still unclear. Inspired by structural reconstruction in charging process, nanoporous Co2P/CoOOH prepared dealloying anodic oxidation is reported as an NO3RR, remarkable catalytic (ammonia yield rate: 1.93 mmol h-1 cm-2, Faradaic efficiency: 94.18%) high cathodic efficiency 34.51%. Additionally, assembled delivers power density 31.99 mW cm-2 charge-discharge stability. In-situ spectroscopy investigation reveals generation Co2P/Co3O4 heterosturcture through synergetic redox involving cobalt species ions which enhances approach potassium-ionized water improves kinetics regulating NO2- *NH2 generation. Density functional theoretical calculation further illustrates that heterostructure optimizes adsorption *NO intermediate enables energetically favorable rate-limiting *NOH formation step. unique activation mode cobalt-based would provide new insights designing efficient electrocatalysts battery.
