Abstract

Photocatalysts that apply semiconductor materials to asphalt mixtures are promising technologies because they can alleviate air pollution. Functional asphalt mixtures with photocatalytic functions can provide significant environmental and social benefits by decomposing pollutants such as gases and oils adsorbed on the surface due to certain reactions triggered by sunlight photons. In this paper, as a literature study on the application of a photocatalyst of an asphalt mixture to reduce nitrogen oxide (NOx), nitrogen oxide (NOx) is reduced by applying a method of spray coating titanium dioxide (TiO₂) on the surface of the asphalt mixture or a modified aggregate coating method of titanium dioxide (TiO₂).
