NOVELTY - Preparing graphene coated aluminum hydroxide nano composite material comprises e.g. (1) adding graphite oxide (0.1-0.5 g) to 150 ml of sodium-phosphorus-tungsten-vanadium(Na4PW11VO40) (0.1-0.3M) solution, and stirring at room temperature at 200 revolutions per minute (rpm) for 20 minutes; (2) adding aluminum acetate Al(CH3COO)3 (1-2 g) and 1 g poly(styrene)-block-poly(ethylene glycol) (PS-PEG) resin to the resulting solution, adjusting the pH to 9-11 with sodium hydroxide (0.5 M), and heating to 60-80 degrees C, stirring; (3) cooling the resulting solution to room temperature, introducing into a photoreactor, irradiating and reacting by an YLS-2000 laser, and reacting for 6 hours; (4) placing the resulting emulsion in a 150 ml volume ratio of deionized water: n-butanol of 1:1 in a mixture, ultrasonically processing at 80-120 W, 30-50 KHz for 2-3 hours, suction-filtering, washing the filter cake with deionized water until constant quality; and (5) vacuum drying the filter cake, and grinding. USE - The method is useful for preparing graphene coated aluminum hydroxide nano composite material. ADVANTAGE - The method is economic, simple and rapid, and does not require any photocatalyst or reducing agent, thus realizes the large-scale production of green and stable graphene-coated aluminum hydroxide nanocomposite material. DETAILED DESCRIPTION - Preparing graphene coated aluminum hydroxide nano composite material comprises (1) adding graphite oxide GO (0.1-0.5 g) to 150 ml of sodium-phosphorus-tungsten-vanadium(Na4PW11VO40) (0.1-0.3M) solution, and stirring at room temperature at 200 revolutions per minute (rpm) for 20 minutes; (2) adding aluminum acetate Al(CH3COO)3 (1-2 g) and 1 g poly(styrene)-block-poly(ethylene glycol) (PS-PEG) resin to the resulting solution, adjusting the pH to 9-11 with sodium hydroxide (0.5 M), and heating to 60-80 degrees C, stirring at 300 rpm for 3 hours; (3) cooling the resulting solution to room temperature, introducing into a photoreactor, irradiating and reacting by an YLS-2000 laser, and reacting for 6 hours to obtain a black emulsion; (4) placing the resulting emulsion in a 150 ml volume ratio of deionized water: n-butanol of 1:1 in a mixture, ultrasonically processing at 80-120 W, 30-50 KHz for 2-3 hours, suction-filtering, washing the filter cake with deionized water until the quality is constant; and (5) vacuum drying the filter cake is at 50-80 degrees C for 8-10 hours, and grinding the dried filter cake to obtain a graphene-coated aluminum hydroxide nanocomposite material.
