Congratulations to Hyunho, Sungwoo, Sameer, Shankar and Ari for their new publication in Science: “Water harvesting from air with metal-organic frameworks powered by natural sunlight”.
The paper reports the design and demonstration of a device based on porous metal-organic framework-801 [Zr 6O 4(OH) 4(fumarate) 6] that captures water from the atmosphere at ambient conditions using low-grade heat from natural sunlight below one sun (1 kW 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.
