The Photocatalyst Museum
About the Museum
The photocatalitic reaction of titanium dioxide(TiO2) was first discovered
by our research group in 1967. Since then, it has been applied to a wide range
of technological fields utilizing its antibacterial, self-cleaning, and deodorization
properties. Photocatalyst has been utilized not only in the industrial applications,
but it has also been utilized in our every day applications.
This museum was established to promote the photocatalyst technologies to the
public and to contribute to the further development of the photocatalyst industry.
I hope that this museum will become a medium to promote this attractive technology
to the general public, from a junior high school student to general consumers,
and raise their interest in general science and technologies.
Please enjoy the museum and experience the advancing technology.

Characteristic reactions of photocatalysts
(1)Decomposition of Organic Matter
When TiO2 is exposed to the light (UV light), radicals which have very strong ability to decompose organic matters, are produced. Such radicals react with and decompose organic materials which cause odors and dirty stains. Radicals also have an ability to kill germs and viruses.
(2)Superhydrophilicity
When TiO2 is exposed to the light (UV light), the surface of the TiO2 becomes hydrophilic (easy to wet the surface without being droplets). This property of TiO2 could prevent fogging of glasses or mirrors. For tiles, all the dirt can be easily removed with water.
