Nanomaterials describe, in principle, materials of which a single unit is sized (in at least one dimension) between 1 to 1000 nanometres (10−9 meter) but usually is 1 to 100 nm (the usual definition of nanoscale).
A crucial part of artificial photosynthesis is water oxidation — separating the hydrogen from the oxygen. EU-funded scientists designed metal-based catalysts to efficiently mimic natural processes for a greener future.
