Efficient electroreduction of CO₂ to C₂₊ products on CeO₂ modified CuO.

ABSTRACT: Electrocatalytic reduction of CO₂ into multicarbon (C₂₊) products powered by renewable electricity offers one promising method for CO₂ utilization and promotes the storage of renewable energy under an ambient environment. However, there is still a dilemma in the manufacture of valuable C₂₊ products between balancing selectivity and activity. In this work, cerium oxides were combined with CuO (CeO₂/CuO) and showed an outstanding catalytic performance for C₂₊ products. The faradaic efficiency of the C₂₊ products could reach 75.2% with a current density of 1.21 A cm^-2. In situ experiments and density functional theory (DFT) calculations demonstrated that the interface between CeO₂ and Cu
