A material found in toothpaste, sunscreen, solar cells and at Wimbledon also devours air pollutants.
Imagine a building coated in a substance that not only allows the building to clean itself after a good rain, but also breaks down the molecules of pollutants in the air. Titanium dioxide is found in a very wide variety of things and is now being added to concrete and coated on to aluminium panels in an effort to help in the battle against pollution.What material can you find in toothpaste, sunscreen, solar cells, on the baseline at Wimbledon, in a Roman church, and along a tunnel in Brussels? Full marks if you guessed titanium dioxide, a nearly ubiquitous but wholly unsung material.
