▎ 摘　　要

NOVELTY - Preparing graphene-titanium dioxide-vanadate photocatalytic functional fabric comprises (i) subjecting the pretreated fabric to plasma treatment, (ii) immersing the plasma-treated fabric in the graphene oxide dispersion, removing excess liquid from the fabric by extrusion, crimping the fabric with graphene oxide dispersion, coating with polyethylene film and subjecting to microwave treatment, (iii) immersing the treated fabric in a titanium dioxide hydrosol, removing excess liquid from the fabric by extrusion, and subjecting the fabric to plasma treatment and ultraviolet irradiation treatment respectively, and (iv) immersing treated fabric in bismuth nitrate, ammonium metavanadate, in a bismuth vanadate sol prepared from glacial acetic acid, citric acid, nitric acid or polyvinylpyrrolidone, removing excess liquid from the fabric by extrusion, crimping the fabric with bismuth vanadate sol coating with polyethylene film and subjecting to microwave treatment to obtain final product. USE - The method is useful for preparing graphene-titanium dioxide-vanadate photocatalytic functional fabric. ADVANTAGE - The prepared fabric: has excellent photocatalytic efficiency under visible light. The method: has excellent purification effect and is environmentally friendly.
