It is challenging to construct non-Cu catalysts toward CO2 electroreduction (CO2ER) ethanol with high selectivity due the difficulty in adjusting active sites for controlling evolution of reaction intermediates. In this work, Sb-doped CeO2 nanospheres are constructed tune intermediates on selective generation. The primary one Sb site and two Ce undergo fluctuations oxidation states during CO2ER, which promotes *CO*OH formation conversion linear *COL further C–C coupling produce ethanol. optimal Sb5.0%-CeO2 can convert as a single liquid product over 50% broad potential range from −0.5 −1.0 V. Remarkably, it exhibits an Faradaic efficiency 70.5 ± 1.2% at −0.7 V stable operation 48 h. This work provides insights into catalyst design CO2ER selectivity.
