NOVELTY - The method for preparing environmentally-friendly textile/graphene/bismuth ferrite composite catalytic material, involves immersing textile fiber in saturated dispersion of graphene oxide, drying, washing, placing in reducing agent solution, heating at 50-80 degrees C for 0.5-1 hour, cleaning, drying to obtain textile fibers/graphene, adding textile fiber/graphene in solution of bismuth(III) nitrate and ferric nitrate, stirring, adding sodium hydroxide and urea, hydrothermally reacting at 120-180 degrees C for 3-8 hours, washing after cooling and drying to obtain final product. USE - Method for preparing environmentally-friendly textile/graphene/bismuth ferrite composite catalytic material. ADVANTAGE - The method enables simple preparation of environmentally-friendly textile/graphene/bismuth ferrite composite catalytic material with excellent purifying effect.
