摘要：
The application of solid oxide electrolysis cell in CO2 electroreduction is a hot research topic at present, but the development of low-cost catalysts with high catalytic activity has always been a challenge for this work. Herein, we use NiCu alloy nanoparticles to modify the perovskite LSCM electrode to build a metal-oxide active interface to obtain high catalytic performance. At 850 degrees C, 4.66 mL min(-1) cm(-2) CO productivity and 97.7% Faraday current efficiency were obtained. In addition, the current remained stable during the 100 h long-term test, indicating that the active interface has the dual effect of improving catalytic performance and maintaining cell durability.
