Converting gaseous nitric oxide (NO) to ammonia (NH3) is important because of its environmental and industrial implications. The electrochemical transformation nitrogen (N2) NH3 faces several challenges, including a slow reaction rate low Faradaic efficiency (FE). This study presents an innovative approach by integrating NO elimination production reduction (NORR) under ambient conditions. Co Mo-based catalysts were investigated for the continuous diluted gas (1%) within proton exchange membrane (PEM) cell In NORR tests conducted without catholyte, CoMo-NC demonstrated notable performance, achieving yield 23.2 × 10−10 mol s−1 cm−2 at −2.2 Vcell FENH3 94.6% −1.6 Vcell, along with enhanced durability. Notably, this performance represents one highest achievements gas-phase room temperature.

Electrocatalytic reduction of nitric oxide (eNORR) represents a promising and sustainable resource strategy. The process is effective at both mitigating anthropogenic air pollution producing ammonia (NH3) in manner that environmentally reliant on renewable energy sources. In this study, series Cu, Ni metal A-site doped nanospinel composites CuxNi1–xCo2O4 (x = 0, 0.5, 0.9, 1) were synthesized as highly efficient electrocatalysts for NO reduction. experimental results catalytic activity showed Cu0.5Ni0.5Co2O4 exhibited maximum Faraday efficiency (FE) 92.73% −0.9 V vs reversible hydrogen electrode (vs RHE), with NH3 production rate 99.12 mmol g–1 h–1 room temperature. Microscopic characterization indicated the distinctive nanorod structure effectively increased surface area, promoted electron/ion transport, exposed more active sites. X-ray photoelectron spectroscopy (XPS) demonstrated interaction between metals could enhance charge transfer inhibit evolution reaction (HER). theoretical analysis comprehensively enhanced was primarily attributed to incorporation Cu doping, which facilitated modification electronic NiCo2O4. Furthermore, synergistic effect sites significantly stable adsorption intermediate *NHO catalyst surface. This work offers guidance facilitates friendly synthesis design spinel catalysts exhibiting superior performance.
