Method for preparing three-dimensional carbon-based electro-catalysis metallic oxide electrode

The invention belongs to the field of preparation of electrode materials in the electro-catalysis advanced oxidized wastewater treatment, and discloses a method for preparing a three-dimensional carbon-based electro-catalysis metallic oxide electrode. The method comprises the steps that firstly, a three-dimensional carbon-based material is selected as a base material and cleaned; secondly, a metallic oxide electroplate liquid or impregnation liquid is prepared; thirdly, the cleaned three-dimensional carbon-based material is placed in the metallic oxide electroplate liquid, at a certain temperature and electric current density, the three-dimensional carbon-based material as an anode is subjected to electrolytic deposition, or the cleaned three-dimensional carbon-based material is placed in the metallic oxide impregnation liquid and subjected to impregnation and calcination, and the three-dimensional carbon-based electro-catalysis metallic oxide electrode is prepared. By means of the method, the three-dimension
