Photo-catalytic concrete is a formulation of concrete used as pavers and other structural concrete that includes titanium dioxide as an admixture or superficial layer. Titanium dioxide is a heterogeneous photocatalyst that uses sunlight and moisture to absorb and render oxides of nitrogen into nitrate ions , which are then either washed away by rain or soaked into the concrete to form stable compounds.
