    摘要: Fluorine contained within a photocatalyst layer containing titanium oxide and other metallic oxide semiconductors increases the metallic oxide's photocatalytic activity. The described photocatalyst may be in the form of either film, flake, particulate, or fiber. In addition, it can be used for coating the surface of a base material of various forms, such as sheet, film, flake, particulate, bar, or fiber. When using a base material that has an alkaline-containing glass composition, establishing a fluorine-containing layer, such as a layer of fluorine-containing silicon dioxide and other metallic oxide, between the photocatalyst film and the base material can prevent the deterioration of photocatalytic activity of the photocatalyst layer. The fluorine-containing layer functions as an alkaline barrier that controls the diffusion and migration of alkali metallic ions in the glass fibers, such as Na ions, into the photocatalyst layer. Inorganic fiber- and glass sheet-based photocatalyst bearing materials have an excellent capability to decompose rarefied harmful organic gases, and are suitable for use as interior wall and air filters in super clean enclosed spaces and conveyance spaces for semiconductor production, clean rooms for various other purposes, and office and residential buildings, and for other purposes including air cleaning, antibacterial action, anti-fouling action, and defogging of clear sheets (maintaining hydrophilicity).
