Abstract
Cu nanoparticles decorated juncus-derived carbon performs efficiently for electrocatalytic NH3 production via NO2– reduction reaction, capable of achieving a high Faradaic efficiency of 93.2% and a large NH3 yield of 523.5 μmol h−1 mgcat.−1.

Electrocatalytic nitrite reduction to value-added NH3 can simultaneously achieve sustainable ammonia production and N-contaminant removal in natural environments, which has attracted widespread attention but still lacks efficient catalysts. In this work, Cu nanoparticles decorated juncus-derived carbon can be proposed as a high-active electrocatalyst for NO2−-to-NH3 conversion, obtaining a high Faradaic efficiency of 93.2% and a satisfactory NH3 yield of 523.5 μmol h−1 mgcat.−1. Density functional theory calculations were applied to uncover insightful understanding of internal catalytic mechanism.
