▎ 摘　　要

NOVELTY - Preparation of textile fiber/graphene/magnesium ferrite composite environmental-purification catalytic material, involves immersing textile fiber in saturated solution of graphene oxide, drying, washing, adding to a reducing agent solution, reacting at 50-80 degrees C for 0.5-1 hour, cleaning, drying to obtain a graphene/textile fiber, adding the obtained material to ferrous chloride/magnesium chloride solution, stirring, adding sodium hydroxide and urea, hydrothermally reacting at 120-180 degrees C for 3-8 hours, cooling, washing, and drying. USE - Preparation of textile fiber/graphene/magnesium ferrite composite environmental-purification catalytic material (claimed). ADVANTAGE - The method is simple and suitable for industrial production, and provides textile fiber/graphene/magnesium ferrite composite having excellent environmental-purification effect.
