Zusammenfassung:	The invention provides a preparation method of bismuth tungstate nanocomposite. The method is as follows: (1) dissolving Na2WO6.2H2O and sodium oleate in redistilled water, and conducting ultrasound treatment to form a clear liquid; mixing the Bi(NO3)3.5H2O, 1mg / mL graphene oxide and redistilled water, and conducting ultrasound treatment to form a brown uniform liquid; mixing and stirring evenly the two solutions, conducting a hydrothermal reaction, cooling, filtering to obtain a precipitate, washing and drying the precipitate to obtain black rGO/Bi2WO6 nanocomposite; and (2) dispersing the rGO / Bi2WO6 nanocomposite into absolute ethyl alcohol, dissolving silver nitrate in ethylene glycol, mixing the two, and irradiating under xenon lamp to obtain a silver loaded rGO / Bi2WO6 / Ag nanocomposite. The bismuth tungstate nanocomposite provided by the invention has good photosensitization, and has great significance in photocatalytic degradation of organic pollutants.
