Sun-powered water splitter makes hydrogen tirelesslyAs scientists continue to pursue alternative fuels that may enable us to break free of the fossil variety, a group of researchers has taken another step towards directly converting solar energy into fuel, in this case, hydrogen. A new system that converts light and water into hydrogen is less expensive than many others, and the photoelectrochemical platform it uses is more reactive, efficient, and has a much longer lifetime.

Sunlight + water = hydrogen gas, in a new technique that can convert 60 per cent of sunlight energy absorbed by an electrode into the inflammable fuel.
Water Splitting by Visible Light: A Nanophotocathode for Hydrogen Production
- Angewandte Chemie International, Volume 49 Issue 9, Pages 1574 - 1577, 5 Feb 2010, DOI: 10.1002/anie.200906262
Hitting water with a 2 iron: A novel nanophotocathode for hydrogen production is based on a multilayer array of InP quantum dots activated with a synthetic diiron catalyst (see picture), which is related to the subsite of FeFe hydrogenase.
