| 摘 要： | The ever-decreasing fossil fuels and the increasing greenhouse effect have caused substantial concern.Solid oxide electrolyser cell(SOEC)with La0.75Sr0.25Cr_(0.5 )Mn0.5O3-δ(LSCM)as a cathode was used for CO2 electrolysis to CO.In this work,the metal-oxide interface was constructed on the LSCM framework by in-situ exsolution and impregnation,and the uniform distribution of metal nanoparticles on the LSCM framework was confirmed by spectroscopy techniques and electron microscopy techniques.The existence of three-phase boundary promoted the absorption and electrolysis of CO2.(La0.75 Sr0.25)0.9(Cr_(0.5 )Mn0.5)0.9(Ni0.5 Cu0.5)0.1 O3-δ(LSCMNC)showed the best electrolytic CO2 performance at 850℃and exhibited excellent electrocatalytic activity after 100 hours of long-term testing and 8 redox cycles.
