Preparation method of electrochemical filter electrode with three-dimensional pores

A preparation method of an electrochemical filter electrode with three-dimensional pores belongs to the technical field of energy and catalytic materials. The method comprises the steps of: fully mixing molybdenum carbide powder, inorganic mineral clay powder and perlite powder according to the mass ratio of (1.5-8): (1-4): (0-1) to form a material A; fully mixing sodium alginate, polyethylene glycol and methyl cellulose according to a mass ratio of (0.5-3.5): (0.05-0.15): (0.05-1.5) to form a material B; fully mixing the material A, the material B and deionized water according to a mass ratio of 20: (1.5-5): (15-20) to form a plastic mixed material, and aging the plastic mixed material; carrying out compression molding on the obtained plastic mixed material, and naturally air-drying the plastic mixed material; and roasting the plastic mixed material under the protection of inert gas and naturally cooling the roasting product to obtain the electrochemical filter electrode with three-dimensional pores.
