<p>The present invention relates to a multi-functional coating agent using a photoactive nanocomposite material having air pollutants purification and self-cleaning functions. The present invention uses the photoactive nanocomposite material, in which a photocatalyst and a nanocrystal meal oxide adsorbent are combined, to manufacture the multi-functional coating agent having a better pollutant removal property than conventional photocatalyst coating agents. The multi-functional coating agent is coated on blocks near roads, external walls of buildings, various facilities, tunnels, underpasses, and the likes, removes various gas phase harmful substances such as NOx, volatile organic compounds, and the likes, and has the self-cleaning function by a hydrophilic function of the photocatalyst.</p> |
