Smog eating coating Posted on November 24, 2006 by Robin Apparently materials containing titanium dioxide break down smog. Structures and roads have been coated with this stuff, which has lead to a reduction up to 60% (depending on light and temperature) of smog in that area. The material itself stays clean as well, reducing cleanup costs. There have been no long term studies, and considering reagents usually break down after a while, the coatings may have to be reapplied, but with an increase in price of EUR. 100,- for the facade of a 5 storey building over traditional paint or plaster, this sounds do-able to me.
