Scientists at Nanyang Technological University in Singapore have built a leaf-inspired device that uses sunlight to make hydrogen from seawater.
It turns sunlight into electricity, so it needs no outside power. At the same time, it breaks down hydrazine, an industrial chemical found in some wastewater.
Tests used simulated and real seawater. The device ran steadily for over 72 hours and cut hydrazine to 0.5 parts per billion in 30 hours.
It's still a lab-stage project focused on hydrazine, so it can't turn ordinary seawater into drinking water. The team hopes to work with other substances next.
