A preparation method and an application of a three-dimensional structured electric cathode based on cuprous oxide are provided by the present application. The preparation method includes the following steps: cutting copper foam, sequentially subjecting to ultrasonic treatment with acetone, hydrochloric acid, anhydrous ethanol and deionized water, followed by washing and vacuum drying to serve as an electrode substrate for later use; dissolving sodium acetate and copper acetate in deionized water, fully stirring for completely dissolution to obtain a solution, and adjusting a pH value of the solution to be acidic to serve as an electrodeposition precursor solution; and placing the copper foam in the electrodeposition precursor solution, electrodepositing at a predetermined temperature by using a three-electrode system and a potentiostatic method, followed by taking out, washing, and drying to obtain a catalytic electrode. The electric cathode is applied in fields of electrocatalytic reduction of nitrate and electrocatalytic ammonia production.
