Is difficult. On the other hand, in recent years, attention has been paid to titanium dioxide (TiO 2 ), which causes a photocatalytic reaction by receiving light even at room temperature. According to this titanium dioxide, a photocatalytic reaction is caused by receiving light, and nitrogen oxides and the like are generated. It is known that the contaminants are changed and retained by a photocatalytic reaction, and the retained substances are removed by washing with water. The present invention has been devised by focusing on such titanium dioxide, and an object of the present invention is to purify contaminated air on a highway without taking up space and without deteriorating aesthetics. It is to provide a method.

The surface area of the sound insulation wall is very large, which allows the surface layer to have an extremely large area, without taking up space, and
It is possible to effectively purify the contaminated air on the highway before spreading out of the highway without impairing the aesthetic appearance.
