Electrochemical　carbon　dioxide　reduction　reaction　(CO2RR)　can　produce　value-added　hydrocarbons　from　renewable　electricity,　providing　a　sustainable　and　promising　approach　to　meet　dual-carbon　targets　and　alleviate　the　energy　crisis.　However,　it　is　still　challenging　to　improve　the　selectivity　and　stability　of　the　products,　especially　the　C2+　products.　Here　we　propose　to　modulate　the　electronic　structure　of　copper　oxide　(CuO)　through　lattice　strain　construction　by　zinc　(Zn)　doping　to　improve　the　selectivity　of　the　catalyst　to　ethylene.　Combined　performance　and　in　situ　characterization　analyses　show　that　the　compressive　strain　generated　within　the　CuO　lattice　and　the　electronic　structure　modulation　by　Zn　doping　enhances　the　adsorption　of　the　key　intermediate　(CO)-C-star,　thereby　increasing　the　intrinsic　activity　of　CO2RR　and　inhibiting　the　hydrogen　precipitation　reaction.　Among　the　best　catalysts　had　significantly　improved　ethylene　selectivity　of　60.5%　and　partial　current　density　of　500　mAcm(-2),　and　the　highest　C2+　Faraday　efficiency　of　71.47%.　This　paper　provides　a　simple　idea　to　study　the　modulation　of　CO2RR　properties　by　heteroatom　doped　and　lattice　strain.
