New MOF harvests up to 0.7 litres of water per day in the Mojave Desert – the driest place in North America

Metal–organic frameworks (MOFs) harvest water in arid conditions like no other material. However, their water harvesting abilities have been limited to one cycle per day. Now, a team led by Omar Yaghi at the University of California Berkeley, US, has designed and synthesised a new aluminium-based MOF that overcomes these hurdles, collecting 10 times more water and performing up to 150 cycles per day.
