Solar-driven water generation is a sustainable treatment technology, helping to relieve global scarcity issues. However, this technology faces great challenges due the high energy consumption of evaporation yielding low rates. Here, covalent organic framework (COF)/graphene dual-region hydrogel, containing hydrophilic and hydrophobic regions in one material, developed through facile situ growth strategy. The COF covering parts graphene regions. Through accurate control both wetting regions, hybrid hydrogel shows effective light-harvesting, tunable wettability, optimized content, lowered demand for vaporization. Acting as solar absorber, exhibits steam rate 3.69 kg m-2 h-1 under 1 sun irradiation (1 kW m-2), which competes well with other state-of-the-art materials. Furthermore, evaporator can be used produce drinkable from seawater sewage, demonstrating potential treatment.
