Due to the scarcity of clean water, there is an increased relevance in accessing clean and renewable water resources. One such perspective method, sorption-based atmospheric water harvesting, collects atmospheric water as an alternative to ground and surface water sources and allows water recyclability without additional energy resources. Metal-organic frameworks (MOFs) are proposed as excellent porous materials for the capture and storage of small molecules, including water, owing to their large pore volume, high surface area, and chemical and structural tunability. Here a zwitterionic MOF (ZW-MOF) was designed, synthesized, and studied for its advanced water adsorption performance; displaying selective water adsorption and desorption capabilities. The ZW-MOF’s adsorptive properties are tested in controlled low and high humidity environments over multiple cycles, demonstrating its regenerative ability and high working capacity.
