Atmospheric water harvesting (AWH) emerges as a promising means to overcome the water scarcity of arid regions, especially for inland areas lacking liquid water sources. Beyond conventional system engineering that improves the water yield, novel moisture-harvesting materials provide new aspects to fundamentally promote the AWH technology benefiting from their high tunability and processability. Innovative material and structural designs enable the moisture harvesters with desirable features, such as high water uptake, facile water collection and long-term recyclability, boosting the rapid development of next-generation AWH. In this Perspective, we first illustrate the sorption mechanism, including absorption and adsorption for moisture-harvesting materials and summarize fundamental requirements, as well as design principles of moisture harvesters. Recent progress on material and structural designs of moisture harvesters for AWH is critically discussed. We conclude with prospective directions for next-generation moisture harvesters to promote AWH from scientific research to practical application.

大气集水:材料和结构设计的回顾
大气集水(AWH)是克服干旱地区缺水的一种有前途的手段,特别是对于缺乏液态水源的内陆地区。除了提高水产率的常规系统工程之外,新型的水分收集材料还提供了新的方面,从而从根本上推动了AWH技术的发展,这得益于其高可调性和可加工性。创新的材料和结构设计使集水器具有所需的功能,例如高吸水率,集水方便和可长期回收利用,从而促进了下一代AWH的快速发展。在此透视图中,我们首先说明了吸附机理,包括对水分收集材料的吸收和吸附,并概述了基本要求以及水分收集器的设计原理。批判性地讨论了用于AWH的水分收集器的材料和结构设计的最新进展。我们总结了下一代水分收集器的前瞻性指导,以将AWH从科学研究推广到实际应用。
