Abstract Hydrogels are emerging as promising candidates for solar-driven interfacial evaporation in water purification. Our research introduces a graphite polyvinyl alcohol hydrogel (GPVA) evaporator designed as a photothermal conversion interface, showcasing high performance with an evaporation rate of 2.43 kg m−2 h−1 and an efficiency of 91.9% under solar irradiance of 1 kW m−2. The layered graphite structure of the GPVA hydrogel enhances its ion and dye adsorption capabilities, effectively removing fluoride, iodine, and other contaminants from water. In cyclic evaporation tests, the GPVA hydrogel evaporator demonstrated remarkable stability and long-term durability, maintaining an evaporation rate of 2.43 More >
