英文摘要	Despite the boom in atmospheric water harvesting (AWH) techniques used to deal with the challenge of clean water shortage, few studies focus on hygroscopic materials that can indicate a moisture change in real time. Here, a moisture-indicating hygroscopic aerogel working in a broad range of relative humidities (RHs) and with fast sorption kinetics is designed for solar driven sorption-based AWH by integrating ethanolamine-decorated CoCl2 (E-CoCl2), microfibrillated cellulose (MFC) and LiCl-decorated polypyrrole (Cl-ppy). The specimen can visually indicate the sorption process in real time while harvesting moisture, achieving a flexible response to changes in environmental humidity and solar radiation. Fabricating an open, unordered, interconnected skeleton in E-CoCl2 using MFC can effectively enhance its sorption kinetics and also prevent the leakage of liquefied salt solution. The specimen has water sorption capacities of 0.39-2.05 kg kg(-1) under RH 25-85% within 3.5 h and can quickly desorb within 1.5 h under 1 sun. An AWH device can conduct 3 sorption/desorption cycles within 9 h during one day outdoors and produces 2.81 kg(water) kg(sorbent)(-1). This strategy is a promising approach to enable sustainable water delivery without geographical and hydrological limitations, especially for the landlocked communities and arid areas.
