▎ 摘  要

NOVELTY - Manufacturing photodegradable materials, preferably zinc oxide-titanium dioxide/graphene aerogel materials for treating organic pigments for environmental sector comprises preparing ingredients as input materials including graphene oxide, zinc acetate dihydrate, ethanol, sodium hydroxide, titanium isopropoxide, acetic acid, poly(vinyl alcohol) and malic acid, zinc oxide was synthesized by hydrothermal method, synthesizing zinc oxide-titanium dioxide/graphene aerogel materials by co-precipitation method, in the process of synthesizing poly(vinyl alcohol) and malic acid to add as a crosslinker to form graphene aerogel block. USE - The method is useful for manufacturing photodegradable materials, preferably zinc oxide-titanium dioxide/graphene aerogel materials for treating organic pigments for environmental sector. ADVANTAGE - None given.
