It is still challenging to develop an effective strategy simultaneously enhance the activity and stability of electrocatalysts for electrocatalytic nitrate reduction reaction (eNO3RR). Herein, taking metallic cobalt as example, it demonstrated that construction low-coordinated nanosheets (L-Co NSs) by H2 plasma etching electrodeposited (Co can greatly eNO3RR.

Abstract The electrocatalytic reduction of nitrate (eNO 3 − RR) to ammonia (NH ) across varying pH is great significance for the treatment practical wastewater containing nitrate. However, developing highly active and stable catalysts that function effectively in a wide range remains formidable challenge. Herein, hierarchical carbon‐based metal‐free electrocatalyst (C‐MFEC) winged carbon coaxial nanocables (W‐CCNs, situ generated graphene nanosheets outside layer with abundant topological defects from pristine nanotubes, CNTs), prepared through moderate oxidation CNTs subsequent introduction defects. W‐CCNs feature functional separation properties, an inner core facilitates efficient charge transfer, while outer shell composed layers enriched characterized by distinct atom configurations, which play crucial role promoting adsorption NO , dissociation water, N─H bond formation. This innovative design enables C‐MFEC exhibit outstanding performance eNO RR, operating efficiently NH yield rates 49.5, 75.3, 88.1 g h −1 cat. acidic, neutral, alkaline media, respectively. Such metrics not only outshine C‐MFECs but also rival or surpass those certain metal‐based catalysts.

Abstract Electrochemical nitrate reduction reaction (NO 3 RR) can effectively alleviate pollution and simultaneously realize ammonia electrosynthesis at room temperature. However, it remains a significant challenge for NO RR to achieve high Faradic efficiency in full concentration range.
