Solid　oxide　electrolytic　cells　(SOECs)　get　much　attention　because　of　their　ability　to　efficiently　convert　electric　energy　into　chemical　energy.　Traditional　cathode　materials　have　problems,　such　as　low　catalytic　activity,　easy　coking,　and　aggregation.　In　this　study,　we　proposed　to　take　CeO2,　which　has　excellent　oxidation-reduction　and　dispersion　ability　to　metal　nanoparticles,　as　the　base;　under　reduction　conditions,　Ni-Cu　alloy　nanoparticles　were　precipitated　and　anchored　on　its　surface　to　construct　an　active　metal-oxide　interface　to　improve　the　electrochemical　reduction　ability　of　CO2　in　SOEC　and　anticoking　performance.　CO　yield　of　SOEC　assembled　with　this　material　as　a　symmetrical　electrode　at　a　temperature　of　850　degrees　C　and　an　applied　voltage　of　1.8　V　is　4.83　mL.min(-1).cm(-2),　which　is　168%　higher　than　that　of　a　pure　CeO2　electrode.　Additionally,　no　carbon　deposition　was　observed　after　the　reaction.　This　work　provides　an　important　reference　for　improving　the　performance　of　the　cathode　materials.
