Chemical catalytic oxidation perforated plate

The invention relates to the technical field of malodorous gas treatment, in particular to a chemical catalytic oxidation porous plate, which is prepared by the following steps: adding a certain amount of foaming agent into a boehmite raw material, carrying out reverse molding to prepare a plate with a certain thickness, airing, and calcining in a kiln at 850-1000 DEG C to form an AL2O3 aluminum plate; taking 340g of water, stirring at room temperature, adding 400g of 50% Na2S2O8 solution, dropwise adding 250g of 20% H2SO4 solution, adding 10g of 0.1% CoSO4 solution, and stirring for 10 minutes to prepare a mixed aqueous solution of 20% Na2S2O8-0.01% cobaltous sulfate and 1000g of 5% sulfuric acid for later use; immersing the porous Al2O3 plate into a graphene oxide alcohol solution for 10minutes, then lifting and airing, and drying at the temperature of 150 DEG C to prepare a graphene oxide porous Al2O3 plate; immersing the graphene oxide porous Al2O3 plate into a 20% sodium persulfate-0.01 cobaltous sulfate
