Riverside have developed the shingles to clean the air
A team of students from the University of California have developed a tile coating that removes up to 97% of nitrogen oxide from the air.
The study group used to cover tiles with different concentrations of titanium dioxide. Then the roof covering was placed in a cell, which is connected to a source of nitrogen oxides and a device that reads concentrations of this compound. They used ultraviolet light to simulate sunlight, which activates the titanium dioxide and lets him break nitrogen oxides. The researchers found: ceramic tile with a titanium dioxide coating was removed from 88 to 97 percent of nitrogen oxides. At the same time, students are not found much of a difference the removal of nitrogen oxide at different concentrations of the dioxide. The most important factor is surface area, not the quantity of the environmental component in the coating.
