Abstract: The shortage of fresh water is one of the great challenges facing the world nowadays. The photothermal water purification has attracted great attention due to its low energy consumption, environmental friendliness and cost-effectiveness. Herein, the cotton towel/polydopamine/redox graphene oxide/Fe3+ (CT-PDA/rGO-Fe3+) composite fabric was fabricated via using PDA-modified waste Cotton towel as the base, and evenly loading rGO and Fe3+ by soaking and constant temperature oscillation. At the irradiation intensity of 1 KW/m2, the surface temperature of the composite fabric could rise to 61°C within 1 min. After 20 cycles, the saturation temperature could be maintained. These results showed that the composite fabric has good photothermal properties and stability. Meanwhile, the composite fabric showed high water purification efficiency (~ 1.201 kg/m2·h). This solar desalination simulator prepared on the basis of waste cotton towel has a simple preparation process and good solar steam efficiency, which shows great potential in the field of desalination.
