Electrochemical reconstruction impacts the surface structure of electrocatalysts and is challenging to control in CO2 electroreduction. Here, by regulating a carbonate shell around an oxide catalyst, the reconstruction is guided towards an abundant low-coordinated structure, achieving a C2+ Faradaic efficiency of 82.8 ± 2.2% at a current density of 2 A cm−2.
