Nanoparticles and light can purify water

Abstract:
Scientists have used nanotechnology to develop a more efficient way of using light to purify water even in the dark.

Light is often used as a water purifier and existing methods rely on processes stimulated by ultraviolet (UV) light.

But UV accounts for just five per cent of daylight so a method using visible light which accounts for almost half is more desirable.

Now researchers from the Shenyang National Laboratory for Materials Science in China and the University of Illinois have developed a photocatalyst that uses visible light to kill bacteria.

The catalyst is made from a grid of titanium oxide fibres impregnated with nitrogen. When light photons hit the grid a positive charge is created which splits water molecules, producing a substance deadly to microbes.
