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).
EU-funded scientists developed new material approaches to improve the photocatalytic capability of titanium dioxide (TiO2). The developed thin-film catalysts are decontaminating water more efficiently.
