▎ 摘　　要

NOVELTY - A cellulose/graphene oxide/titania hydrogel is prepared by adding sodium hydroxide and urea to water, mixing to obtain mixed solution, pre-cooling, adding cellulose, stirring to obtain cellulose solution, adding graphene oxide and titania to water, mixing, adding cellulose solution, stirring, casting into film, immersing into dilute sulfuric acid solution for coagulation bath treatment, obtaining hydrogel, and washing. USE - Method for preparing cellulose/graphene oxide/titania hydrogel used for photocatalysis and physical adsorption (claimed). ADVANTAGE - The method is simple, environment-friendly and suitable for industrialization.
