Smog Eating Photocatalytic Coatings:
The Delhi government will conduct a time-bound study on “smog-eating” photocatalytic coatings in Delhi to combat air pollution.
- Smog Eating Photocatalytic Coatings is designed to neutralise harmful gases like nitrogen dioxide and volatile hydrocarbons that contribute to toxic air.
- It usually uses titanium dioxide as a coating which has advantages for being low-cost and chemically stable.
- Titanium dioxide is also known for its compatibility with traditional construction materials.
- Photocatalytic activity helps fight pollution by breaking down harmful substances and organic waste into less toxic or harmless matters using light energy, thereby making air and water cleaner.
- Smog is used to refer to a type of air pollution caused by a combination of smoke (and other pollutants) and fog.
