Nanoparticles to clean drinking water
Abstract:
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.
The photocatalyst becomes more efficient when nanoparticles of the metal palladium are added as these hold the positive charge for longer.
