Abstract
We report a sulfonated covalent organic framework (COF) capable of atmospheric water harvesting in arid conditions. The isothermal water uptake profile of the framework was studied, and the network displayed steep water sorption at low relative humidity (RH) in temperatures of up to 45 °C, reaching a water uptake of 0.12 g·g−1 at 10% RH and even 0.08 g·g−1 at just 5% RH, representing some of the most extreme conditions on the planet. We found that the inclusion of sulfonate moieties shifted uptake in the water isotherm profiles to lower RH compared to non-sulfonated equivalents, demonstrating well the benefits of including these hydrophilic sites for water uptake in hot arid locations. Repeated uptake and desorption were performed on the network without significant detriment to its adsorption performance, demonstrating the potential of the sulfonated COF for real-world implementation.
