Desalination water + graphene oxide
WebNov 2, 2015 · The reason desalination is possible in the first place is that when diffused in water, salt ions bond with water molecules, thereby creating a larger entity. But the difference in size compared to a free water molecule is still frustratingly small. “The challenge is to find the sweet spot of about 0.8 nanometers,” Grossman says. WebNov 21, 2016 · More strikingly, because of minimized heat loss, high efficiency of solar desalination is independent of the water quantity and can be maintained without thermal insulation of the container. A foldable graphene oxide film, fabricated by a scalable process, serves as efficient solar absorbers (>94%), vapor channels, and thermal …
