It has to go through a very difficult process. In addition, the material of the fluorescent lamp must also be one that transmits light of 254 nm, and expensive quartz glass must be used for that, which leads to an increase in cost. For photocatalyst, 25
Since the photocatalytic reaction occurs only with light having a high energy of 4 nm (4.88 eV), it is also disadvantageous in terms of energy cost. Note that this 254 nm light is generally used as a germicidal lamp and is harmful to the human body, especially to the eyes. Therefore, it is not preferable to use light of this wavelength.

The "plate glass" in the present invention includes, for example, glass used as an interior material in the fields of buildings, automobiles and the like. That is, glass provided in an opening of a living space such as a house or office, glass provided for the transparency of the outside world or the inside of the living space, glass used for introducing natural light from the outside world or as a barrier to the outside world, etc. There is.

み合わせを選択してもかまわない。When the titanium oxide photocatalyst is carried on the surface of the plate glass, it is desirable to bond the interface with a Ti--O--Si bond. As described below, the Ti-O-Si bond can be used for bonding by using a solution of a titanium oxide precursor that becomes titanium oxide by heating and an organic resin as a starting material. As the titanium oxide precursor, titanium alkoxide, titanium chloride, titanium sulfide, titanium acetate and the like can be used. However, when alcohols are used as a compatible solvent, titanium is used because of the compatibility with the organic resin. When alkoxide or water is used as a compatible solvent, titanium chloride, titanium sulfide or titanium acetate is preferably selected. However, when the precursor and the organic resin are compatible with each other, any combination may be selected.

もない。As described above, a solution prepared by dissolving the selected precursor and the organic resin in a compatible solvent is used as a starting material for producing a titanium oxide photocatalyst. That is, in order to obtain a photocatalyst from this starting raw material, for example, a plate glass serving as a carrier may be dipped in this raw material liquid, or the raw material liquid may be applied or sprayed on the plate glass, dried and then baked. This drying is preferably performed at 150 ° C. or lower for 30 minutes or more. The temperature rising rate from the liquid loading to the drying and the drying to the firing is preferably 10 ° C./min or less. In addition, it is necessary to consider the heat resistance of the base material in the final baking step,
Baking at a temperature of 50 ° C. or lower is preferable. The photocatalyst-supporting plate glass of the present invention is obtained as described above, but is not limited to these methods.
It goes without saying that in the case of flat glass such as float glass, spray application may be performed online during glass production.

る。Since the photocatalyst such as titanium oxide has a small band gap of 3 to 3.2 eV, it can be easily excited by light having a small energy. The light of fluorescent lamps and incandescent lamps, which are usually used in daily life, contains almost no ultraviolet light having high energy of 4.5 eV or more, but contains light having energy more than the band gap of titanium oxide. Therefore, the photocatalyst used in the present invention is easily excited by these ordinary lights to cause a photocatalytic reaction. Also,
The sunlight that passes through the ordinary transparent glass is 3.7 eV
The energy light is as follows, but since it also has energy higher than the band cap of titanium oxide, the photocatalyst used in the present invention is easily excited by sunlight passing through these plate glasses to cause a photocatalytic reaction. Due to this photocatalytic reaction, odors such as nicotine, tar, tar and the like that are produced in the room such as cigarette odor, pet odor and toilet odor are easily decomposed.

When titanium oxide as a photocatalyst is supported on this and the interface between the surface of the plate glass and the photocatalyst is bonded by a Ti-O-Si bond, an organic resin and a precursor of titanium oxide are used as starting materials for the photocatalyst. A Ti-O-Si bond is formed on the surface of the plate glass by using a mixed solution and by the combustion heat generated by the oxidative decomposition reaction of the organic residues constituting them. Thus, the base material and the photocatalyst are joined together by a strong bond, and the photocatalyst does not fall off. According to the photocatalyst-supporting plate glass produced by the above method, the photocatalytic reaction progresses by the light generated from a normal lighting fixture such as a fluorescent lamp or an incandescent lamp and the sunlight passing through the plate glass, and the indoor odor such as cigarette odor in the surroundings The offensive odor generated in is decomposed and removed.

トイレ臭等の種々の臭いを分解除去することができる。According to the present invention, since the photocatalyst is carried on the surface of the plate glass, it is possible to easily decompose a bad smell such as a cigarette odor in a room without providing a special deodorizing device. Further, the photocatalyst used in the present invention causes a photocatalytic reaction by low energy light of 4 eV or less such as fluorescent lamps and incandescent lamps obtained in a normal room and sunlight passing through plate glass. Therefore, nicotine, tar, tar, etc. It is possible to decompose and remove various odors such as cigarette odor, pet odor and toilet odor.
