A self-cleaning wall paint
A self-cleaning wall paint
A breakthrough in catalysis research leads to a new wall paint that cleans itself when exposed to sunlight and chemically breaks down air pollutants. Typically, beautiful white wall paint does not stay beautiful and white forever. Often, various substances from the air accumulate on its surface. This can be a desired effect because it makes the air cleaner for a while - but over time, the colour changes and needs to be renewed.
