The invention provides an electrocatalytic reduction catalyst and its preparation method and application. The preparation method of the electrocatalytic reduction catalyst includes: adding copper nitrate hydrate, aluminum nitrate hydrate and barium nitrate into deionized water, and placing them in an ice-water bath for ultrasonic dispersion. Form precursor solution; add cetyltrimethylammonium bromide to the alkaline aqueous solution to obtain a first mixed solution, and mix the first mixed solution and the precursor solution evenly to obtain a second mixed solution, forming a Cu-Al hydroxyl precursor with Ba evenly embedded; wash the Cu-Al hydroxyl precursor evenly embedded in Ba with a mixture of ethanol and water, remove cetyltrimethylammonium bromide, and obtain a solid powder after drying; subjecting the solid powder to thermal reduction treatment to obtain the electrocatalytic reduction catalyst. By introducing barium single atoms into the copper-aluminum composite oxide for doping modification, the present invention can effectively promote the C-C coupling reaction to improve the Faradaic efficiency of the ethylene product.
