Abstract
["Single-atom catalysts (SACs) are gaining increasing recognition because of their superior catalytic prop-erties for various reactions. However, the performance of SACs is often limited by the lack of neighboring metal centers to cooperate in catalysis. Herein, a synergetic interaction between neighboring Cu atoms of a few-atom catalyst (FAC) on graphdiyne (GDY) is found to greatly enhance the production of acetate in the CO electroreduction reaction relative to Cu SACs. In a 1.0 M KOH electrolyte, this Cu FAC exhibits an acetate Faradaic efficiency of 53.8 +/- 1.5%, an ultrahigh relative purity of up to 97 wt % for liquid products, and excellent stability over 23 h continuous electrolysis at -0.8 V versus reversible hydrogen electrode. Theoret-ical studies suggest that the intersite catalytic com-munication between two neighboring metal atoms confined in each pore of GDY facilitates the formation of acetic acid through either stepwise hydrogenation of CH2CO* or the direct reaction of H2O with CH2CO*. Our study demonstrates the unprecedented synerget-ic catalysis of Cu FAC in promoting the selective CO electroreduction toward acetate production.","[GRAPHICS]","."]
