The invention discloses a carbon-loaded copper-zinc catalyst as well as a preparation method and application thereof. The preparation process of the catalyst is simple, firstly, a precursor is designed and prepared, the characteristic that Zn < 2 + > and 2-methylimidazole can form a stable metal organic framework material ZIF-8 is utilized, Cu < 2 + > is wrapped in a pore channel structure of the ZIF-8, fixation and dispersion of Cu are achieved, and then the carbon-loaded copper-zinc catalyst is obtained through high-temperature calcination; the catalyst can be used for an electrocatalytic co-reduction reaction of nitrate and carbon dioxide to synthesize a high-added-value amine product (ammonia and urea), or can be used for an electrochemical dechlorination reaction of an organic chlorine-containing compound (dichloromethane), and has an application prospect in the field of comprehensive environmental treatment. 本发明公开了一种碳负载铜锌催化剂及其制备方法与应用；本发明催化剂的制备工艺简单，首先设计并制备前驱体，利用Zn2+可与2-甲基咪唑形成稳定金属有机框架材料ZIF-8的特点，将Cu2+包裹于ZI
