Abstract

Water collection from moisture in air, i.e., atmospheric water harvesting, is an urgent future need for society. It can be used for water production everywhere and anytime as an alternative water source in remote areas. However, water harvesting and collection usually relies on desalination, fog, and dewing harvesting, which are energy intensive. In this respect, metal–organic frameworks (MOFs) have broad applicability for water harvesting in water-scarce areas; therefore, the current discussion focuses on this approach. Furthermore, recent progress on MOFs for moisture harvesters is critically discussed. In addition, the design, operation, and water harvesting mechanisms of MOFs are studied. Finally, we discuss critical points for future research for the design of new MOFs as moisture harvesters for use in practical applications.

Graphical Abstract

MOF adsorbents offer excellent operating capacity in various temperature and pressure ranges. Rational water harvesters can thus be developed by adjusting structural properties such as the porosity, functionalities, and metal centers, thereby enabling new devices to produce water even in remote areas.

利用多孔金属-有机骨架(mof)从空气中获取水分

从空气中的水分中收集水分，即大气集水，是未来社会的迫切需要。它可以随时随地用于生产水，作为偏远地区的替代水源。然而，水的收集通常依赖于海水淡化、雾和露水的收集，这些都是能源密集型的。在这方面，金属-有机框架对缺水地区的集水具有广泛的适用性;因此，当前的讨论集中在这种方法上。此外，本文还对水分采集器mof的最新进展进行了讨论。此外，还对mof的设计、运行和集水机理进行了研究。最后，我们讨论了设计用于实际应用的新型mof集湿器的未来研究要点。mof吸附剂在各种温度和压力范围内都具有良好的操作能力。因此，合理的水收集器可以通过调整孔隙度、功能和金属中心等结构特性来开发，从而使新设备即使在偏远地区也能采水。

期刊介绍： Topics in Current Chemistry is a journal that presents critical reviews of present and future trends in modern chemical research. It covers all areas of chemical science, including interactions with related disciplines like biology, medicine, physics, and materials science. The articles in this journal are organized into thematic collections, offering a comprehensive perspective on emerging research to non-specialist readers in academia or industry. Each review article focuses on one aspect of the topic and provides a critical survey, placing it in the context of the collection. Selected examples highlight significant developments from the past 5 to 10 years. Instead of providing an exhaustive summary or extensive data, the articles concentrate on methodological thinking. This approach allows non-specialist readers to understand the information fully and presents the potential prospects for future developments.
