Abstract

Titanium dioxide works as a photocatalyst oxidizing most of organic matter strongly under the light which has a wavelength around 400 nm or shorter than 400 nm. Organic matter is decomposed to CO₂, H₂O and so on. In these days, there are many products with the functions of deodorization, sterilization, and self-cleaning in the market. Photocatalyst TiO₂ has extremely small diameter around 10 to 20 nm. The reason of being nano order is large surface area. For instance, the average diameter of 150 nm TiO₂ is estimated about 10 m²⁄g, while 7 nm TiO₂ has a greater surface area of 320 m²⁄g. We found that titanium dioxide which has diameter around 10 nm works most effective when then are applied as a coating pigment. We have developed unique “photocatalyst paper” with air purifying effect. TiO₂ surface modified with decomposable binder by TiO₂ were used to avoid chalking. The photo catalytic paper includes new technologies such as preventing chalking and printability control.
