One‐pot self‐assembled TiO2/graphene/poly(acrylamide) superporous hybrid for photocatalytic degradation of organic pollutants

ABSTRACT We report the development of TiO 2 /graphene/poly(acrylamide) superporous hybrid by a radical polymerization reaction and explore its environmental application as photocatalyst of organic pollutants. During the polymerization reaction, graphene nanosheets and TiO 2 nanoparticles homogeneously distribute on the hydrogel, in which TiO 2 nanoparticles with a uniform size are densely anchored onto graphene and self‐assembled into different structures with various graphene contents. The resultant TiO 2 /graphene/poly(acrylamide) superporous hybrid experiences tremendous adsorption toward dye pollution before photodegradation, and it also displays similar photodecomposition efficiency with pristine TiO 2 . Moreover, the TiO 2 /graphene/poly(acrylamide) superporous hybrid is recyclable, which demonstrates the potential of hybrid as an attractive photocatalyst for wastewater treatment. © 2018 Wiley Periodicals, Inc.
