光触媒及びその製造方法並びにそれを用いた光触媒コート剤、光触媒分散体、光触媒体
Document Type and Number:
Japanese Patent JP5055271
Kind Code:
B2
Abstract:
This invention provides a photocatalyst having excellent activity under the application of light, for example, from a white fluorescent lamp with a wavelength of 400 to 500 nm. The photocatalyst comprises at least iron oxyhydroxide and titanium oxide. Titanium oxide exhibits photocatalytic activity upon the absorption of light with a wavelength of 400 to 500 nm by iron oxyhydroxide. The photocatalytic activity is such that the acetaldehyde decomposition reaction rate constant upon the application of light from the white fluorescent lamp is at least about twice the decomposition reaction rate constant of acetaldehyde with titanium oxide as measured under the same conditions.
