The invention provides a nano-copper array cathode for reductive degradation of organic pollutants as well as preparation and application thereof. Under a condition of lower cathode constant electric potential, through one-step electrodeposition, nano-copper arrays are loaded on surfaces of substrate materials such as three-dimensional foam copper, the obtained nano-copper sheet arrays are uniformly distributed, tightly arranged and difficult to fall off; the dimension length of the nano-copper sheet is less than 500nm, the width is less than 100nm and the thickness is less than 10nm; the prepared nano-copper array cathode is applied to organic pollution water treatment, precious metal palladium with high price is replaced, so that the manufacturing cost of an electrode is greatly reduced while the degradation efficiency of the organic pollutants is improved at the same time. According to the nano-copper array cathode disclosed by the invention, the process is simple, raw materials are low in cost and easy to obtain, and the possibility is provided for magnification scale production.
