Nitrogen Defects in Porous Carbons with Adjacent Silver Nanoclusters for Efficient CO₂ Reduction

Abstract Electrochemical CO 2 reduction is an environmentally sustainable way for conversion and utilization, the development of which needs highly efficient catalysts. Ag‐based materials are one kind electrocatalyst that catalytically active to CO. In this work, Ag clusters were fabricated on nitrogen‐doped porous carbon nanomaterials by a high‐temperature annealing method. The well‐dispersion sites carbons (Ag/NC) promoted production. As result, Ag/NC showed maximum Faradaic efficiency 94 % at −0.7 V versus reversible hydrogen electrode (vs RHE) room temperature. addition, good stability, remained stable about 90 vs RHE 12 h. Density functional theory calculation indicated cooperation N‐dopings effectively reduced activation energy barrier relative evolution reaction thus electrocatalytic molecules This method provides new idea synthesis catalysts with higher activity, selectivity stability.
