Access to clean, safe drinking water is a necessity that’s
worryingly not being met in many parts of the world. A new study has used a
material called a metal-organic framework (MOF) to filter pollutants out of
seawater, generating large amounts of fresh water per day while using much less
energy than other methods.
MOFs are extremely porous materials with high surface areas
– theoretically, if one teaspoon of the stuff was unpacked it could cover a
football field. That much surface area makes it great for grabbing hold of
molecules and particles.
