The invention relates to a preparation method and application of a CuO Sn/Zn three-dimensional core-shell structure electrode material, porous foamy copper is used as a conductive substrate, a one-dimensional CuO nanorod array is synthesized on the surface of the conductive substrate in situ, and after CuO nanorods are annealed, Sn/Zn bimetal is deposited on the surfaces of the CuO nanorods through an electrodeposition method to form a core-shell structure. The CuO (at) Sn/Zn three-dimensional core-shell structure electrode is applied to a working electrode catalyst material for electrochemical reduction of carbon dioxide, shows excellent performance of reduction into formic acid and long-term stability, and has quite excellent industrialization value. 本发明涉及一种CuO@Sn/Zn三维核壳结构电极材料的制备方法、应用，以多孔泡沫铜作为导电基底，在其表面原位合成了一维CuO纳米棒阵列，CuO纳米棒经过退火后通过电沉积法在表面沉积Sn/Zn双金属形成核壳结构。CuO@Sn/Zn三维核壳结构电极应用于二氧化碳电化学还原的工作电极催化剂材料，表现出优异的还原为甲酸的性能和长期稳定性，具有相当优秀的产业化价值。
