Here, we present a single-atom Pb-alloyed Cu catalyst (Pb1Cu) that can exclusively (~96% Faradaic efficiency) convert CO2 into formate with high activity in excess of 1 A cm–2. The Pb1Cu electrocatalyst converts CO2 into formate on the modulated Cu sites rather than on the ...
Cu nanoparticles with different GB densities reveals that the specific activity of CO reduction depends linearly on the ratio of GB surface terminations (Fig.5c). Finally, GB terminations on the electrode surface are more active for CO2RR than for HER; this finding was confirmed by scanning elect...
In that second reactor, formate, H2 and CO2 are consumed by the microorganisms, forming acetate and methane. Compared to simple buffer electrolyte, catalytic activity of copper was improved in the presence of microbial growth medium, likely due to EDTA (Ethylenediaminetetraacetic acid) present in ...
Electrocatalytic reduction of CO2 into multicarbon (C2+) products is a highly attractive route for CO2 utilization; however, the yield of C2+ products remains low because of the limited C2+ selectivity at high CO2 conversion rates. Here we report a fluorine-modified copper catalyst that exhibit...

Cu demonstrates a unique capability towards CO2 electroreduction that can close the anthropogenic carbon cycle; however, its reaction mechanism remains elusive, owing to the obscurity of the solid–liquid interface on Cu surfaces where electrochemical reactions occur.Using a genetic algorithm method in ad...
CuCO3 + 2HCl → CuCl2 + CO2 + H2O In the above preparation, the hydrate of the salt crystallizes, precipitates, and may be dehydrated by heating under vacuum. 9.6 Reactions When heated above 300°C, copper(II) chloride partially decomposes to copper( I) chloride and chlorine: 2CuCl2→ 2Cu...
