Energy from light and water: New photocatalytic method for the clean production of hydrogen from water

(PhysOrg.com) -- Hydrogen-powered fuel cells and solar energy are the best hope for a more environmentally friendly and resource-sparing energy supply in the future. A combination of the two is considered to be particularly `clean`: the production of hydrogen by splitting water with sunlight. Previous approaches to this have suffered from high costs and the limited lifetime of their catalytic systems.
