▎ 摘  要

NOVELTY - A chemically-modified titanium dioxide photocatalyst is obtained by loading preset amount of titanium dioxide on graphene and sulfonated cobalt phthalocyanine complex. USE - Chemically-modified titanium dioxide photocatalyst is used for decomposing organic pollutants in water. ADVANTAGE - The chemically-modified titanium dioxide photocatalyst has low forbidden bandwidth, enhanced electron transfer efficiency, wide visible light response range of 460 nm or more, and excellent oxygen activation efficiency to quickly decompose organic pollutants, and can be prepared industrially by a simple and economical method. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of chemically-modified titanium dioxide photocatalyst, which involves adding 0.1667 mg graphene and 8.33 mg sulfonated cobalt phthalocyanine in a mass ratio of 1:50 to 1 ml water, ultrasonically reacting for 8-10 hours to obtain a composition, stir-mixing butyl titanate, ethanol, and acetic acid in a volume ratio of 17:34:4.8 to obtain a mixed solution, adding 14.2 mg complex composition to 55.8 ml mixed solution, stirring to obtain a sol-gel, reacting the sol-gel at 160-200 degrees C for 16-20 hours, washing the product with 5 %mass hydrochloric acid and water, and drying at 80 degrees C for 8 hours.
