Figure Abstract

Caption

The surface modification of Cu nanoparticles with 1,4-benzenedicarboxylic acid (BDC) ligands with different functional groups can effectively tune the dilute CO2 electrolysis performance. The electron-withdrawing -F group results in a high Faradaic efficiency of 67.9% towards multicarbon (C2+) products under a 15% CO2 feed, which is ascribed to the reduced electron density of Cu active sites that enhances *CO adsorption and lowers C−C coupling energy barrier.
