LSCM perovskite is a promising ceramic cathode for direct CO2 electrolysis in solid oxide electrolysis cells (SOECs), but its application is limited by insufficient catalytic activity and stability. Herein, a novel strategy is proposed to improve electrolysis properties by modifying La0.75Sr0.25Cr0.5Mn0.5O3-delta-Gd0.2Ce0.8O2-delta (LSCM-GDC) backbone with Cu nanocatalyst. The metal-oxide interfaces between Cu NPs and ceramic backbone effectively increase the catalytic active sites and oxygen vacancy concentration, thus facilitating CO2 transport and reduction process. Consequently, Cu decorat...
