Abstract | The invention discloses a graphene quantum dot loaded CuO catalyst for producing ethylene through high-current carbon dioxide electro-catalysis as well as a preparation method and application of the graphene quantum dot loaded CuO catalyst. The method comprises the following steps: inserting two high-purity graphite carbon rods into a potassium bicarbonate solution, clamping an electrode holder, electrifying to electrolyze carbon materials on the surfaces of the graphite rods to strip graphene quantum dots, centrifugally filtering to take supernate, filling the supernate into a dialysis bag, and dialyzing to remove potassium bicarbonate salt to obtain a graphene quantum dot aqueous solution; and mixing the graphene quantum dot aqueous solution with CuO nanosheet solid powder, adding ethanol, stirring, centrifugally filtering to obtain a precipitate, and drying to obtain the graphene quantum dot loaded CuO catalyst. The graphene quantum dot loaded CuO catalyst prepared by the invention effectively solves the p |
