摘要
Abstract In recent years, the porous sorbent‐assisted atmospheric water harvesting (AWH) method has emerged as an effective approach for solving water crises without geographical restrictions. However, there is a limited array of porous adsorbent materials that can be used for AWH, which are inadequate to meet the needs under different climatic conditions. In light of this, herein, we synthesize a new crystalline porous organic salt (CPOS; denoted as CPOS‐6) possessing a dual hydrogen bond system and verify its applicability toward AWH for the first time. Unlike other reported CPOSs, CPOS‐6 displays an S‐shaped water sorption isotherm owing to the presence of the dual hydrogen bond system. Under simulated drought conditions in Xinjiang Uygur Autonomous Region, CPOS‐6 exhibits long‐term water adsorption‐desorption cycling stability, low water desorption temperature, and ultrarapid adsorption‐desorption kinetics. The results confirm that CPOS‐6 is an effective sorbent material for AWH.
