Electrochemical CO2 reduction reaction (CO2RR), which converts CO2 into value-added chemicals, offers a promising pathway toward carbon neutrality. Considerable efforts to convert CO2 into C2+ chemicals have focused on steering CO2RR pathways through the rational design of Cu-based electrocatalysts that promote *CO dimerization. A critical challenge in CO2RR is catalyst reconstruction under operating conditions, which inevitably alters the precisely engineered active sites under operating conditions. Here, I will present our recent efforts to elucidate the fundamental principles governing the reconstruction of electrocatalysts and to harness this dynamic process for targeted product formation. We found that *CO-induced metal dissolution-redeposition dynamics, together with miscibility-governed atomic rearrangement, play a pivotal role in surface reconstruction. We extend our investigation to examine the impact of electrolyte pH and ligand engineering on catalyst reconstruction.
