AB  - Electrochemical carbon dioxide reduction reaction (CO2RR), powered by advanced technologies such as solid oxide electrolysis cells (SOEC), is a promising method to convert CO2 into valuable carbon-based products using renewable electricity. The high chemical stability of CO2 requires catalysts to exhibit both high activity and stable electrocatalytic performance. However, catalysts that deliver high performance in CO2RR are rare and still require further improvement. Here, we report a strategy that can efficiently enhance catalyst activity through Zn doping, which introduces active frustrated Lewis pairs (FLP) to improve the catalyst's ability to activate small molecules. A high current density of −1.85 A cm−2 at 800 ℃ under a bias voltage of 1.5 V was achieved using the Sr2Fe0.8Zn0.2MoO6-δ (SFZn0.2M) cathode with pure CO2 feeding gas, surpassing previously reported results for perovskite oxide cathodes. This SOEC device also demonstrates excellent stability, with negligible degradation over tests lasting up to 110 h.
