Multifunctional 3D GO/g-C3N4/TiO2 foam for oil-water separation and dye adsorption
Oily wastewater causes serious pollution to the environment and has aroused widespread concern. Herein, non-toxic, environmentally friendly, multi-functional superwetting GO/g-C 3 N 4 /TiO 2 (GCT) foam was prepared via hydrothermal treatment and freeze-drying methods. The as-prepared GCT foam could simultaneously separate oil–water mixtures and adsorb water-soluble organic dyes, both the separation efficiency and adsorption efficiency are higher than 98%. In addition, the GCT foam have the ability to separate various oil-in-water emulsions with separation efficiency of higher than 99%. Meanwhile, the as-prepared GCT foam was able to degrade oil pollution and showed excellent antioil-fouling capability. The as-prepared multifunctional GCT foam is expected to have broad prospects in the treatment of oily wastewater and the adsorption of water-soluble organic pollutants, which may be providing a new strategy for the oily wastewater remediation.
