▎ 摘　　要

NOVELTY - Preparing textile fiber/graphene/tin oxide composite environmental catalytic material comprises (i) impregnating textile fiber into the saturated dispersion liquid of the graphene oxide, drying and cleaning, and then put it in the reducing agent solution for 0.5-1 hours at 50-80 degrees C, washing and drying to obtain the textile fiber/graphene, and (ii) adding textile fiber/graphene to sodium hydroxide and trisodium phosphate solution, stirring, then adding tin(II) chloride and urea, reacting at 120-180 degrees C for 3-8 hours, cooling, washing and drying to obtain final product. USE - The method is useful for preparing textile fiber/graphene/tin oxide composite environmental catalytic material (claimed). ADVANTAGE - The method is simple and is suitable for industrial production; the composite material has good environment purifying effect.
