The synthesis of nitrate (NO3−) via electrocatalytic nitric oxide oxidation reaction (NOOR) is a green and efficient strategy for nitrogen fixation, which has great advantages over conventional synthesis. Notably, it also presents promising solution the remediation NO pollutants. In this study, structure–performance correlations α-, β-, δ-MnO2 catalysts were investigated. These three polymorphs MnO2 exhibited disparate surface chemistries, adsorption capabilities, NOOR catalytic activities. 1.0 M KOH electrolyte, α-MnO2, characterized by its large-sized (2 × 2) one-dimensional tunnel structure, demonstrated most outstanding performance, achieved remarkable NO3− yield 665.2 mg·h−1·mgcat−1 at potential 1.9 V, along with excellent stability durability. Furthermore, Zn-NO system was constructed, employing α-MnO2 as anode Zn plate cathode. This innovative setup integrated an energy storage electrochemical capture, yielding production rate 265.5 mg·h−1·mgcat−1. density functional theory calculations confirm performance activity different crystal forms MnO2.
