▎ 摘　　要

NOVELTY - Preparing textile fiber/graphene/bismuth germanium oxide (Bi2GeO5) composite environmental 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) using the graphene/textile fiber adding into bismuth(iii) nitrate (Bi(NO3)3) 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 germanium oxide composite environmental 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 germanium oxide (Bi2GeO5) composite environmental 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 germanium oxide composite environmental catalytic material.
