The present invention relates to an air-cleaner fan coated with a photocatalyst. According to the present invention, the air-cleaner fan coated with a photocatalyst is prepared by surface-modifying crystallized titanium oxide nanoparticles, and preparing a coating solution using the surface-modified titanium oxide nanoparticles, to coat a fan of an air-cleaner. An objective of the present invention is to provide an air-cleaner fan coated with a photocatalyst, which has the surface coated with titanium oxide, which is a photocatalyst, to purify and sterilize the air.본 발명은 광촉매가 코팅된 공기청정기팬에 관한 것이다.본 발명은 결정화된 산화티타늄 나노입자를 표면개질하고, 표면개질된 산화티타늄 나노입자를 이용하여 코팅액을 제조하여 공기청정기의 팬에 코팅하여 이루어지는 광촉매가 코팅된 공기청정기 팬을 제공한다.
