But recently, it was shown that spiking TiO2 with nitrogen ions gives it photocatalytic capabilities in UV light and visible light.

By coating their fabric with nano particles made from this new N-TiO2, the researchers have created a fabric that self-cleans in the presence of a very broad spectrum of light.
