Deciphering true active sites under identical mass transport conditions is crucial for understanding catalytic mechanisms. By establishing uniform mass transfer and implementing controlled experiments to eliminate interfering factors, the research team identified Cu(100) grain boundaries as the key sites driving efficient C2+ production. Advanced characterization and theoretical calculations confirmed these sites facilitate asymmetric C–C coupling between *CHO and *CO intermediates, providing critical insights for rational catalyst design.
