Sunlight-powered material harvests water from air using UV light
A team of chemists at the University of Iowa has developed a light-activated crystal structure that can pull water from the air and store it inside nanoscale cavities, offering a new approach to atmospheric water harvesting. The material is built from metal-organic frameworks, or MOFs, which are porous structures formed by linking metal atoms with organic molecules. In this case, researchers designed a lattice that initially had no usable caviti…
Light reshapes metal-organic framework to harvest airborne water
Chemists at the University of Iowa have created a three-dimensional lattice that captures water from the air and stores it. In a new study appearing in the Journal of the American Chemical Society, researchers describe a millimeter-scale structure made of metal atoms connected by two types of organic molecules. When exposed to ultraviolet light, the material undergoes a chemical reaction that changes its shape, creating cavities throughout the l…
Getting water out of the air is not a new idea, but so far most methods have required electricity, cooling units or elaborate technology. Chemists at the University of Iowa have now taken a different path: They have developed a three-dimensional crystal lattice that chemically restructures under the influence of ultraviolet light, forming cavities that absorb and hold water molecules from the ambient air.Image: University of Iowa Metal scaffolds…
Chemists from the University of Iowa have created a three-dimensional network that captures water from the air and stores it. In a new study published in the Journal of the American Chemical Society, the researchers describe a structure at the millimetre scale consisting of metal atoms connected by two types of organic molecules. When exposed to [...]
