Scientists used a new photo-electrode made from nanoparticles of the elements lanthanum, iron and oxygen, to split water into its constituent parts - hydrogen and oxygen – using sunlight. The hydrogen can then be used as a fuel, with the potential to power everyday items such as homes and vehicles.
