Embodiment 1
[0027] Take 100g of wood charcoal and crush it to 8-12μm; dissolve 50g of sodium hydroxide in 50mL of water, mix it evenly with the wood charcoal, and dry it under vacuum; The temperature was raised to 780°C and kept for 2 hours; after cooling to room temperature, the activated product was washed to neutrality, then 6M hydrochloric acid was added to reflux for 2 hours, and then washed with deionized water to neutrality; 4g of calcium carbonate whiskers, 300mL of 0.6wt% concentration of graphene aqueous dispersion, and 2 g of melamine was added to it, ultrasonically stirred for 1 h, and then spray-dried; the above material was placed in a reduction furnace, and the temperature was raised to 800 ° C at a rate of 10 ° C / min under the protection of hydrogen and kept for 2 h ; After the temperature drops to room temperature, the graphene super-purifying air composite material is obtained.
