Strong Locking of Edge Ni−N₄ Sites for *COOH: New Breakthrough in Acidic CO₂RR Achieving FEco > 94% and Energy Efficiency of 44%
First Author: Ziwen Mei (Central South University)Corresponding Authors: Zhang Lin, Min Liu (Central South University) Research BackgroundElectrochemical CO₂ reduction to CO serves as an important bridge connecting renewable electricity with chemical feedstocks. Acidic media can completely avoid carbonate precipitation, benefiting device longevity; however, the hydrogen evolution reaction (HER) dominates in strong acids. Although single-atom Ni−N₄ … Read more
