▎ 摘  要

NOVELTY - Preparation of bismuth tungstate nanocomposite, involves dissolving sodium tungstate dihydrate and sodium oleate in distilled water, ultrasonically processing, ultrasonically mixing bismuth nitrate pentahydrate, graphene oxide, and distilled water, mixing both liquids, reacting, cooling, filtering, washing, drying to obtain black graphene oxide/bismuth tungstate nanocomposite, dispersing the nanocomposite in ethanol, dissolving silver nitrate in ethylene glycol, mixing both, and irradiating to obtain silver-loaded graphene oxide/bismuth tungstate nanocomposite. USE - Preparation of bismuth tungstate nanocomposite used for photocatalysts used for decomposing organic pollutants (all claimed). ADVANTAGE - The method provides bismuth tungstate nanocomposite having excellent photocatalytic activity with respect to decomposition of organic pollutants. DETAILED DESCRIPTION - Preparation of bismuth tungstate nanocomposite, involves dissolving sodium tungstate dihydrate and sodium oleate in distilled water, ultrasonically processing, ultrasonically mixing bismuth nitrate pentahydrate, 1 mg/mL graphene oxide, and distilled water to form a brown liquid, mixing both prepared liquids, seal-reacting, cooling, filtering to obtain precipitate, washing the precipitate, drying to obtain black graphene oxide/bismuth tungstate (rGO/Bi2WO6) nanocomposite, dispersing the nanocomposite in anhydrous ethanol, dissolving silver nitrate in ethylene glycol, mixing both, and irradiating with xenon light to obtain silver-loaded graphene oxide/bismuth tungstate nanocomposite.
