▎ 摘  要

NOVELTY - Visible light-sensitive photocatalyst comprises core comprising bismuth tungstate and a shell containing nitrogen-doped graphene oxide quantum dots (NGQD) and cyanide nitrogen surrounding the core. USE - The visible light-sensitive photocatalyst is useful in composition for removing organic carbon in wastewater (claimed) and in various fields i.e. products, home appliances, vehicles, paints, air treatment, water treatment, medical treatment and agriculture. ADVANTAGE - The visible light-sensitive photocatalyst increases demand for photocatalyst targeting total organic carbon and has antibacterial and deodorizing functions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for producing a visible light-sensitive photocatalyst comprising (a) mixing a complex of NGQD and cyanide nitrogen, sodium tungstate dihydrate and bismuth(III) nitrate pentahydrate, (b) heat-treating the dispersion and (c) drying the heat-treated dispersion and pulverizing the product.
