NOVELTY - Preparing textile fiber/graphene/bismuth molybdate/bismuth tungstate composite environment catalytic material comprises e.g. impregnating textile fiber with graphene oxide saturated dispersion, placing in reducing agent solution, reacting at 50-80 degrees C for 0.5-1 hours, cleaning, and drying to obtain textile fiber/graphene, adding textile fiber/graphene into bismuth(iii) nitrate and trisodium phosphate solution, then adding sodium molybdate, sodium tungstate and urea, carrying out hydrothermal reaction, washing after cooling, and then drying to obtain final product. USE - The method is useful for preparing textile fiber/graphene/bismuth molybdate/bismuth tungstate composite environment catalytic material (claimed). ADVANTAGE - The method is simple and environmentally friendly, and is suitable for industrial synthesis. DETAILED DESCRIPTION - Preparing textile fiber/graphene/bismuth molybdate/bismuth tungstate composite environment catalytic material comprises (i) impregnating textile fiber with graphene oxide saturated dispersion, then drying, cleaning, and then placing in reducing agent solution, reacting at 50-80 degrees C for 0.5-1 hours, cleaning, and then drying to obtain textile fiber/graphene, (ii) adding textile fiber/graphene obtained in step (i) into bismuth(iii) nitrate and trisodium phosphate solution, stirring, then adding sodium molybdate, sodium tungstate and urea, carrying out hydrothermal reaction at 120-180 degrees C for 3-8 hours, washing after cooling, and then drying to obtain final product.
