Nitrite (NO2 -) is a dangerous pollutant that often found in groundwater sources and endangers human health. In addition to nitrite removal requirements, electrocatalytic reduction reaction (eNO2RR) holds promise for value-added ammonia (NH3) production at room temperature. this study, solvothermal technique the preparation of nickel phthalocyanine (NiPc) used as highly active electrocatalyst conversion NO2 - NH3 under ambient conditions. The NiPc catalyst shows remarkable Faradaic efficiency (FE) 90.1% -0.9 V versus RHE with maximum yield rate 14667 µg h-1 mgcat. -1 -1.0 0.1 M Na2SO4 containing NaNO2 solution. Furthermore, exhibits exceptional long-term stability during chronoamperometry tests. These findings boost future from sustainable development.

Electrochemical coreduction of carbon dioxide and nitrate offers a sustainable pathway to synthesize value-added urea from greenhouse gas nitrogen-containing waste; however, challenges remain in designing efficient catalysts. Based on the concept "integrative catalytic pairs (ICPs)", catalyst for synthesis is designed by introducing heteroatoms (B C) into M-N-C, where single transition metal dispersed N-doped material. Using two-step theoretical screening strategy, Ni-N3B identified as promising synthesis, with low limiting potential (-0.43 V) small kinetic barrier C-N coupling (0.74 eV) due electronic regulation effects synergy Ni B function enhancing NO3- activation facilitating between gaseous CO2 *NH intermediate. Under guidance these results, our further experimental validation demonstrates that synthesized achieves Faradaic efficiency 51.92% yield rate 32.30 mmol h-1 g-1 at -0.6 V vs RHE. Our work not only identifies an without relying trial-and-error methods but also inspires exploration ICPs-based catalysts electrocatalysis.

Abstract Electrochemical urea synthesis under ambient conditions offers a promising alternative to traditional methods, yet suffers from inefficient production due poor binding of reactants the catalyst surface, leading competitive pathways. In this study, we report an electrochemical route for by dual reduction CO 2 and N gases using iron phthalocyanine (FePc) catalyst. The FePc electrocatalyst showed yield rate 357 µmol h −1 g cat with Faradaic efficiency (FE) 14.36% at −0.4 V versus RHE. This work awareness into development efficient electrosynthesis via C─N coupling.
