Method for removing nitrated nitrogen in water through electro-catalysis

The invention discloses a method for removing nitrated nitrogen in water through electro-catalysis, wherein a porous conductive material with a cuprous oxide film deposited on the surface is used as an electro-catalysis cathode. According to the invention, the process is simple, efficient adsorption and reduction of nitrate in a water body can be achieved without additionally adding Cl and other additives in a catalytic reduction process, the main product is non-toxic and harmless nitrogen, and the method has huge application potential in the actual water body. 本发明公开了一种电催化去除水中硝化氮的方法，是以表面沉积有氧化亚铜薄膜的多孔导电材料作为电催化的阴极。本发明的工艺简单，在催化还原的过程中不需要额外添加Cl-等添加剂，就可以实现对水体中硝酸盐的高效吸附和还原，并且主要产物是无毒无害的氮气，具有在实际水体中应用的巨大潜力。
