Atmospheric water is a resource equivalent to ~10% of all fresh water in lakes on Earth. However, an efficient process for capturing and delivering water from air, especially at low humidity levels (down to 20%), has not been developed. We report the design and demonstration of a device based on a porous metal-organic framework {MOF-801, [ZrO(OH)(fumarate)]} that captures water from the atmosphere at ambient conditions by using low-grade heat from natural sunlight at a flux of less than 1 sun (1 kilowatt per square meter). This device is capable of harvesting 2.8 liters of water per kilogram of MOF daily at relative humidity levels as low as 20% and requires no additional input of energy.
大气水是一种资源，相当于地球上湖泊中所有淡水的 10%左右。然而，一种从空气中高效捕获和输送水的方法，特别是在低湿度水平（低至 20%）下，尚未开发出来。我们报告了一种基于多孔金属有机骨架{MOF-801，[ZrO(OH)(富马酸盐)]}的装置的设计和演示，该装置利用自然阳光中的低品位热能，在低于 1 个太阳（每平方米 1 千瓦）的通量下，在环境条件下从大气中捕获水。该装置能够以低至 20%的相对湿度水平，每天每公斤 MOF 收获 2.8 升水，并且不需要额外的能量输入。
