Titanium dioxide, as a catalyst for light paint pigments, is not only an environmentally safe cleaning agent, but also can save energy and protect environmental resources.
Early Japanese and British scientists applied titanium dioxide to the surface of paving stones on urban roads to clean the road air. Titanium dioxide can be mixed with asphalt to reduce pollutants in the air. When a car passes by, concrete or asphalt containing titanium dioxide can purify the air and eliminate 25% to 45% of nitrogen oxides in vehicle emissions. Coating titanium dioxide on the concrete surface has the same effect of cleaning the air.
