Ag incorporation in atomically precise Au3Ag3Cu6 nanoclusters promotes electrocatalytic nitrate-to-ammonia conversion
Abstract:
A trimetallic Au3Ag3Cu6 nanocluster, obtained by Ag doping of Au3Cu9, exhibits enhanced NO3RR-to-NH3 performance, delivering 90.66% faradaic efficiency at -0.6 V vs. RHE. DFT calculations reveal that Ag incorporation strengthens Au-Ag-Cu electronic synergy, optimizes key intermediate adsorption/conversion, and promotes reaction kinetics.
