Title
Photodegradation of phenol via C3N4-agar hybrid hydrogel 3D photocatalysts with free separation
Abstract

•The agar-C3N4 hybrid hydrogel photocatalysts show 3 dimension network structure.•The hybrid hydrogels show synergistic effect of adsorption and photocatalytic degradation.•The photocatalytic activity of agar-C3N4 was greatly enhanced.•The pollution can be degraded continuously via agar-C3N4 hybrid hydrogels photocatalysts without separation.

The agar-C3N4 hybrid hydrogel photocatalysts with 3 dimension (3D) network structure have been prepared via thermoreversible phase transition of agar. The hybrid hydrogels show high efficient pollutants removal ability by synergistic effect of adsorption and photocatalytic degradation. The removal ability of phenol and methylene blue (MB) by hybrid hydrogel is about 1.3 and 4.5 times of pure g-C3N4 respectively. The pollution can be degraded continuously via agar-C3N4 hybrid hydrogels photocatalysts without separation.
