▎ 摘　　要

NOVELTY - Preparing textile fiber/graphene/bismuth vanadate (BiVO4)/bismuth(iii) oxide(Bi2O3) composite catalytic material comprises e.g. (i) dipping the textile fiber into saturated solution of graphene oxide, drying and washing, then placing into the reducing agent solution at 50-80 degrees C for 0.5-1 hours, then cleaning and drying, (ii) adding graphene/textile fiber into bismuth(iii) nitrate and trisodium phosphate solution, stirring, adding sodium metavanadate, sodium hydroxide and carbamide, and carrying out hydro-thermal reaction, cooling, washing and drying. USE - The method is useful for preparing textile fiber/graphene/bismuth vanadate/bismuth(iii) oxide composite catalytic material (claimed). ADVANTAGE - The method is simple and suitable for industrial production. The composite material has better environmental purification effect. DETAILED DESCRIPTION - Preparing textile fiber/graphene/bismuth vanadate (BiVO4)/bismuth(iii) oxide(Bi2O3) composite catalytic material comprises (i) dipping the textile fiber into saturated solution of graphene oxide, drying and washing, then placing into the reducing agent solution at 50-80 degrees C for 0.5-1 hours, then cleaning and drying to obtain the graphene/textile fiber, (ii) using the resulting graphene/textile fiber adding into bismuth(iii) nitrate (Bi(NO3)3) and trisodium phosphate (Na3PO4) solution, stirring, then adding sodium metavanadate, sodium hydroxide and carbamide, and carrying out hydro-thermal reaction at 120-180 degrees C for 3-8 hours, cooling, washing, and drying to obtain the textile fiber/graphene/ bismuth vanadate/bismuth(iii) oxide composite catalytic material.
