| Abstract:Graphene oxide cellulose aerogel (GO@CA) was prepared by a one-pot method based on the lithium bromide inorganic molten salt system using microcrystalline cellulose as the raw material. The effects of three different Hummers methods on the structure and performance of graphene oxide (GO) were investigated, and the optimal GO was selected for the preparation of GO@CA and its application effect in solar interfacial evaporation was evaluated. The results showed that the GO@CA had a three-dimensional hierarchical pore network, with a light absorption rate of up to 96%~97% in the 300~2 500 nm spectral range. Under 1 kW/m² irradiation, its evaporation rate reached 2.24 kg/(m²·h), and it exhibited excellent cycling stability and seawater desalination capacity. Through the synergistic design of the photothermal component and the porous substrate, this aerogel achieved efficient photothermal conversion and water transport, providing a feasible strategy for solar-driven water purification. |
