Solar vapor generation is emerging as a reliable way to directly transfer solar irradiation to water evaporation. Graphene-based porous photothermal materials are considered as promising absorbers in this system owing to the broadband absorption and excellent photothermal properties. In this paper, a three-dimensional (3D) graphene foam with self-foaming method for solar vapor generation was produced. Abundant porous channels and a hydrophilicity effect are simultaneously achieved by foam formed. The result shows that graphene foam 3.00 wt% at 30 min stirring time can be achieved highest solar water evaporation at 278% compared to foam without GnPs loading at same stirring time. The FESEM detected more porous channels appears at 3.00 wt.% GnPs loading foams. |
