Solid　oxide　electrolysis　cell　as　an　energy　conversion　device,　has　attracted　much　attention　in　recent　years　due　to　its　high　efficiency　and　capacity.　In　this　work,　we　prepare　the　metal-oxide　materials,　Ce0.9(NixCu1-x)0.1O2-δ　(x　=　0–1),　and　alloy　Ni/Cu　nanoparticles　are　exsolved　from　the　CeO2　surface　after　treatment　in　an　H2/Ar　reducing　atmosphere,　which　is　formed　the　metal-oxide　interfaces.　The　current　density　reaches　0.51　A　cm−2　at　700　°C,　1.0　V　and　the　ethane　conversion　rate　is　38.9%　with　the　ethylene　yield　of　24.9%,　and　it　demonstrates　outstanding　stability　even　after　being　operated　continuously　for　a　period　of　one　hundred　hours.　The　material　with　in-situ　precipitation　metal-oxide　interface　shows　significantly　enhanced　ethane　electrolytic　activity,　which　is　also　confirmed　by　density　functional　theory.　This　work　demonstrates　the　potential　application　of　electrochemical　ethane　oxidative　dehydrogenation.　©　2023　Hydrogen　Energy　Publications　LLC
