Yes, you read that right. Paint that eats smog. Or rather, paint that the New Scientist says does this:
“The polysiloxane base is porous enough to allow NOx to diffuse though it and adhere to the titanium dioxide particles. The particles absorb ultraviolet radiation in sunlight and use this energy to convert NOx to nitric acid.
The acid is then either washed away in rain, or neutralised by the alkaline calcium carbonate particles, producing harmless quantities of carbon dioxide, water and calcium nitrate, which will also wash away.”
New Eco Paint, by Millennium Chemicals” will be going on sale in Europe in March, collects the NOx it has converted to nitric acid, and then it is either “washed away in rain, or neutralised by the alkaline calcium carbonate particles, producing harmless quantities of carbon dioxide, water and calcium nitrate”.
Why is it that Europe gets all the cool stuff first? Would it be because this country is the last country on earth to realize that climate change is going to kill us all? Hopefully we can get some Smog Eating Paint over here soon!
