NOVELTY - Graphene air purification materials, comprises 79-95 pts. wt. Camellia oilseed residue carbon, 5-9 pts. wt. tea saponin, 10-25 pts. wt. graphene, 1-5 pts. wt. tea polyphenol and 200-500 pts. wt. deionized water. USE - Used as graphene air purification materials. ADVANTAGE - The purification materials eliminates harmful gas in the air, at the filter rate of PM more than 2.5-99.2, at the same time, formaldehyde in the air; and has good the purifying efficiency of benzene harmful gas by more than 92.7-95.3%. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing air purifying material, comprising (i) mixing Camellia oilseed residue carbide, mixing uniformly into tea saponin, raising the temperature in the atmosphere furnace, for activating, then cooling to the room temperature, to obtain the Camellia oilseed residue activated carbide, taking out, naturally cooling to the room temperature, grinding to obtain the pre-processed powder; (ii) mixing grapheme, placing in de-ionized water, ultrasonically dispersing to uniform, then adding tea saponin, continuously ultrasonically dispersing uniformly, to obtain mixed solution; and (iii) taking the mixed liquid obtained in step (ii), uniformly spraying the pre-treatment powder obtained in step (i), placing into a furnace at 800-1500 degrees C, roasting for 30-60 minutes, then cooling to room temperature, and taking out.
