NOVELTY - The preparation method of textile fiber/graphene/titanium dioxide composite environmental catalytic material involves: (1) impregnating textile fiber with saturated dispersion of graphene oxide, then drying, cleaning, then placing in reducing agent solution, carrying out reaction at 50-80 degrees C for 0.5-1 hour, cleaning, and drying to obtain textile fiber/graphene; and (2) adding textile fiber/graphene to solution of titanium source and trisodium phosphate, stirring, then adding polyethylene glycol 2000 and carbamide, carrying out hydrothermal reaction, cooling, and drying. USE - The method is useful for preparing textile fiber/graphene/titanium dioxide composite environmental catalytic material (claimed). ADVANTAGE - The method enables simple preparation of textile fiber/graphene/titanium dioxide composite environmental catalytic material with high yield. DETAILED DESCRIPTION - The preparation method of textile fiber/graphene/titanium dioxide composite environmental catalytic material involves: (1) impregnating textile fiber with saturated dispersion of graphene oxide, then drying, cleaning, then placing in reducing agent solution, carrying out reaction at 50-80 degrees C for 0.5-1 hour, cleaning, and drying to obtain textile fiber/graphene; and (2) adding textile fiber/graphene obtained in step (1) to solution of titanium source and trisodium phosphate, stirring, then adding polyethylene glycol 2000 and carbamide, carrying out hydrothermal reaction at 120-180 degrees C for 3-8 hours, cooling, washing and drying.
