Abstract:
A photocatalyst for air purification, a photocatalyst film including the photocatalyst, and an air purification device including the photocatalyst. The photocatalyst for air purification includes: a first metal oxide particle having ultraviolet absorptivity, and fluorine bound to a surface of the first metal oxide particle; second metal oxide particles present on the surface of the first metal oxide particle. The use of the photocatalyst for air purification to remove or degrade volatile organic compounds (VOCs) and viruses.
