NOVELTY - 1 g Graphene-doped polyaniline-coated nickel zinc ferrite magnetic nanoparticles are added to high-temperature carbonization reduction device, and 2 g potassium permanganate is added. The temperature reducing device is placed in a muffle furnace at high temperature, calcined from room temperature to 900 degrees C for 4 hours, and cooled to room temperature to obtain graphene-doped polyaniline-coated nickel zinc ferrite mesoporous materials. USE - Manufacture of graphene-doped polyaniline-coated nickel zinc ferrite mesoporous material (claimed) for military stealth material, electromagnetic wave absorbing material and environmental absorbing material for absorbing heavy metals, persistent organic pollutants and other pollutants. ADVANTAGE - The method efficiently provides graphene-doped polyaniline-coated nickel zinc ferrite mesoporous material. DETAILED DESCRIPTION - 0.03 Mol hydrated nickel nitrate (Ni(NO3)2.6H2O), 0.02 mol hydrated zinc nitrate (Zn(NO3)2.6.H2O) and 0.1 mol hydrated ferric nitrate (Fe(NO3)3.9.H2O) were dissolved in deionized water, in 100 ml three-necked flask, ultrasonically dispersed, mixed, and 0.1 mol citric acid is added. The pH of the resultant mixture is adjusted to 7, stirred vigrously for 5 minutes, and transferred to water bath at 65-75 degrees C, and microwave oscillation is carried out until brown-red transparent sol appears. The resultant sol is transferred to a thermostatic oven at 75-85 degrees C and dried to form a dry gel. 1-3 ml Ethanol is added to obtained dry gel, ignited, self-propagating combustion is carried out to obtain nickel-zinc-iron-containing complex oxide (Ni0.6Zn0.4Fe2O4) powder. The resultant powder is placed in a muffle furnace at 550-650 degrees C, calcined for 5 hours, cooled to room temperature, and milled to obtain nickel-zinc-iron-containing complex oxide magnetic nanoparticles. 2 g Graphite is added to 250 ml beaker, 10 ml concentrated nitric acid, 5ml concentrated sulfuric acid, and 5 g potassium permanganate were added, ultrasonically dispersed for 10 minutes, and washed with deionized water. 5ml of concentrated aqueous ammonia is added to the obtained mixture, ultrasonically dispersed for 10 minutes, washed, centrifuged, and 10 ml hydrogen peroxide is added and ultrasonically dispersed for 10 minutes. 5 ml Concentrated hydrochloric acid is added to the obtained mixture, and sonicated for 10 minutes. 10 ml Absolute ethanol is added and sonicated for 10 minutes. The resultant material is then filtered, washed and dried at 90-110 degrees C to obtain graphene. 1 g Nickel-zinc-iron-containing complex oxide magnetic nanoparticles are added to 20 ml 1 mol/L hydrochloric acid solution, and graphene is added and ultrasonically dispersed for 10 minutes, and 2 mL aniline is added, such that the mass ratio of aniline and graphene is 0.5-1.5. The resultant mixture is mechanically stirred for 10 minutes, to obtain solution (A). 5 g Ammonium persulfate is dissolved in 80 mL 1 mol/L hydrochloric acid solution to form solution (B). In an ice bath, under stirring condition solution (B) is added to solution (A), stirred for 11-13 hours, and the precipitate was separated magnetically and washed with deionized water. The resultant mixture is suction filtered, washed with ethanol for three times, and dried at 75-85 degrees C for 22-26 hours to obtain graphene-doped polyaniline-coated nickel zinc ferrite magnetic nanoparticles. 1 g Graphene-doped polyaniline-coated nickel zinc ferrite magnetic nanoparticles are added to high-temperature carbonization reduction device, and 2 g potassium permanganate is added to corundum crucible. The temperature reducing device is placed in a muffle furnace at high temperature, calcined from room temperature to 900 degrees C for 4 hours, and cooled to room temperature to obtain graphene-doped polyaniline-coated nickel zinc ferrite mesoporous materials.
