Abstract
The CuO/CeO2 composites with strong metal-support interaction were synthesised, which can efficiently electroreduct CO2 to C2H4. The Faradaic efficiency (FE) of C2H4 could reach 50.5% with a current density of 18 mA cm−2. The strong metal-support interaction could not only enhance the adsorption and activation of CO2, but also can stablize the CuO.
