Breathe freely with photocatalysis

Photocatalytically active house paints and paving stones improve the air quality of cities. The inhabitants of cities and urban areas have to struggle with air pollution every day. Especially nitrogen oxides, which are formed by the combustion of fossil fuels in automotive engines but also by home heating, are very harmful. These pollutants do not only affect the health, they are in addition involved in the formation of ozone and summer-smog.

Solutions to this problem are photocatalytically active building materials such as house paints and paving stones. Their effect is due to a special...
