PPy-MOF-303@SA aerogel composite adsorbent with vertical channels for atmospheric water harvesting in arid environments: preparation and performance evaluation

PPy-MOF-303@SA aerogel, fabricated via directional freezing, combines alginate, MOF-303, and polypyrrole. It achieves 0.39 g·g −1 uptake at 25 °C and 30% RH in 60 min, with 96.73% desorption under 1 kW·m −2 solar irradiation.
