The invention discloses a Pd/Cu catalyst and a preparation method and application thereof in electrocatalytic reduction coupling, the catalyst is used as a working electrode, the back surface of carbon paper is packaged, Ag/AgCl is used as a reference, a Pt sheet is used as a counter electrode, an electrochemical cell is assembled, and the electrochemical cell is electrified in an aqueous solution for electrocatalytic reaction, so that the adsorption activation of benzaldehyde on the surface of the catalyst is effectively promoted, and the catalytic activity of benzaldehyde is improved. The reduction coupling activity and selectivity of benzaldehyde are improved. In an aqueous solution, the catalyst only requires an electrode potential of-0.40 V relative to a standard hydrogen electrode, and achieves hydrogenation benzoin selectivity of 63.2% and a production rate of 1.27 mmol mg <-1 > h <-1 >. 本发明公开Pd/Cu催化剂及其制备方法和在电催化还原偶联中的应用，催化剂作为工作电极，碳纸背面进行封装，Ag/AgCl作为参比，Pt片为对电极，组装成电化学池，在水溶液中通电进行电催化反应，有效促进了苯甲醛在催化剂表面的吸附活化，提
