In　order　to　enhance　the　conductivity　and　catalytic　efficiency　of　non-noble　electrocatalyst,　an　electrocatalysts　consisting　of　ZnCo　metallic　double　oxide　with　S　doping　embedded　on　V2C　MXene　for　oxygen　evolution　reaction　(OER)　is　synthesized.　Cobalt　serves　as　the　primary　active　site,　while　zinc　contributes　to　improve　conductivity　owing　to　its　high　electronegativity.　Sulfur　doping　plays　a　crucial　role　in　reducing　the　energy　barrier　of　rate　determining　step　of　OER.　The　V2C　MXene　as　a　substrate　can　promote　conductivity　as　well,　resulting　in　synergistic　effect.　The　electrocatalyst　exhibits　a　low　overpotential　of　240　mV　at　10　mA　cm−2　in　alkaline　electrolyte,　surpassing　that　of　IrO2　commercial　electrocatalyst.　The　potential　shows　only　a　minimal　∼5　mV　day　after　72-h　stability　test　at　20　mA　cm−2.　The　current　density　at　1.6　V　vs　RHE　is　2　times　that　of　commercial　IrO2.　Both　theoretical　calculation　and　experimental　result　demonstrate　the　advantage　brought　by　the　incorporation　of　zinc　and　sulfur.　This　work　introduces　a　new　idea　of　synergetic　effect　in　non-noble　metallic　electrocatalysis.　©　2024　Elsevier　B.V.
