Abstract Electrocatalytic nitrite (NO 2 − ) reduction RR) to ammonia (NH 3 is a promising green technology for producing NH with high efficiency. Cobalt macrocyclic complexes have attracted great interest because of their ability selectively convert NO , but suffer from low yields. Herein, cobalt porphyrin conjugated polymer on carbon nanotubes (CoPCOP@CNT) reported display exceptional RR performance large yield 133.39 mg h −1 CoP at −1.0 V and Faradaic efficiency (FE) 98.0% −0.8 V. Utilizing CoPCOP@CNT as the catalyst cathode, Zn‐NO battery exhibits remarkable power density (5.34 mW cm −2 ), open‐circuit voltage (≈1.45 V), FE (94.6%), (29.15 ). The active intermediates reaction pathways CoPCOP in process are revealed by differential electrochemical mass spectroscopy theory calculations. This work highlights potential electrocatalysts based metal porphyrins conversion nitrogenous pollutant into .

Electrochemical nitrite (NO2–) is a promising technology for NO2– removal and sustainable method generating valuable ammonia (NH3), but this process intricate generates other byproducts. In work, we propose facile low-cost the preparation of Cu3Mo2O9 nanosheet array, which can serve as an efficient electrocatalyst reduction to NH3. The morphology be adjusted by controlling synthesis conditions. neutral solution, achieves high NH3 yield 30.46 mg h–1 cm–2 outstanding faradaic efficiency 98.6% with excellent long-term electrochemical stability reduction. Density functional theory calculations further reveal key role (202) surface its possible reaction pathways in electrocatalytic nitrite.
