This article reviews recent progress in AWH sorbent design and study, covering innovative chemistries, integration of sophisticated architectures and functional components, and clarifies the structure-property-performance relationship. Summaries of different sorbents' features and limitations, discussions on applications, and future developments are provided.
Water scarcity caused by climate change and population growth poses a grave threat to human society. Of the different water purification technologies put forward, one presents a promising strategy that is spatially or temporally non-restricted-atmospheric water harvesting (AWH). Here we review recent progress in the design and study of AWH sorbents, ranging from the innovative chemistries to the integration of sophisticated architectures and functional components, and clarify the structure-property-performance relationship that governs the water capture and release processes. Features and limitations of each type of sorbents are summarized to elucidate the optimal working environments and modes. Progress in applications extending from water generation to thermal management and agriculture are discussed. Future developments regarding material modifications, performance measurements, and system optimizations are provided to overcome lingering barriers to sorbent design and implementation.
