  As shown in FIG. 1, the photocatalytic functional body according to the present invention is composed of at least an optical semiconductor powder 2 a, metal fine particles 2 b, and an adsorbing material 3.

Examples of the optical semiconductor powder 2a include TiO ₂ , CdS, CdSe, WO ₃ , Fe ₂ O ₃ , SrTiO ₃ , KNbO _{3 and the} like. Among them, TiO ₂ is chemically stable without being attacked by most acids, bases and organic solvents, and TiO ₂ does not cause poisoning and is not carcinogenic in animal experiments and the like. TiO ₂ is the most preferable from this point.

  Here, the metal powder 2b functions as an electrode in the photocatalytic functional body. As the metal powder forming the electrode, various metal powders such as gold, platinum, copper, etc. can be used in addition to silver. . Since water is required as one of the indispensable elements for the photocatalyst to perform its original function, the metal powder forming the electrode needs to be stable with no change over time in the presence of water. Among the metal powders, platinum is most preferable, but silver is preferable because it is economical and has the characteristics described above, and is non-toxic and itself sterilizable.

The adsorbing material 3 is used for adsorbing and holding objects to be treated such as malodorous substances and harmful substances in addition to bacteria, viruses and molds. Examples of the adsorbing material include one or more selected from the group consisting of ceramic powders such as apatite (apatite) zelite or sepiolite, activated carbon and silk fiber-containing materials, and these may be combined with two or more as necessary. Can be used. Here, as the apatite, hydroxyapatite [Ca ₁₀ (PO ₄ ) ₆ (OH) ₂ ] that selectively adsorbs proteins such as bacteria, viruses, and molds is preferable. Moreover, as a silk fiber containing material, what was shape | molded in the granular form other than silk fiber powder, a gel-like material, etc. are contained. The particle size of these adsorbing materials (when the silk fiber-containing material is powder) ensures a larger surface area and is preferably 0.001 to 1.0 μm, particularly 0.01 to 1.0 μm, considering good deposition workability. 0.05 μm is preferred. The mixing ratio of the optical semiconductor powder and the adsorbing material is preferably 1 to 50 parts by weight, and particularly preferably 10 to 30 parts by weight with respect to 100 parts by weight of the optical semiconductor powder.

  Here, the method for adhering the photocatalytic functional body composed of the above-mentioned photo semiconductor powder, metal fine particles, adsorbing material, etc. on the substrate is not particularly limited, and even if it is adhered by the low temperature spraying method, printing is also possible. It may be adhered to the base material as an ink or paint.

FIG. 1 shows a state in which a photocatalyst is adhered to a substrate surface by a low temperature spraying method. For example, a melting point is formed on a substrate 1 such as a nonwoven fabric, a woven fabric, paper, wood, a ceramic plate, a metal plate, or a plastic plate. A ceramic obtained by melting titanium oxide (TiO ₂ ) fine particles (5 to 50 μm) having a temperature of 2000 ° C. or less and metal fine particles 1 to 10 μm at a temperature of about 2900 to 3000 ° C. by gas spraying using oxygen, acetylene or the like. It has been sprayed. In the thermally sprayed state, the photocatalyst particles 2 are composed of titanium oxide particles 2a that act as one electrode and metal particles such as silver particles 2b that act as the other electrode carried on the titanium oxide particles 2a. The photocatalyst particles 2 form an electrochemical cell, and after spraying, become flat laminated particles of 30 to 40 μm, and adhere to the substrate 1 by the anchor effect while melting due to the high temperature of the gas. In the low temperature spraying method by gas spraying using oxygen, acetylene, etc., the gas torch for injecting the molten photocatalyst particles and the substrate are moved relative to each other so that the substrate surface does not exceed 50 ° C. Thermal spraying is possible even on paper, cloth and the like. However, because of gas spraying, the melting point of the raw material powder used is limited to 2000 ° C. or less. Plasma spraying is also possible by adjusting the relative speed between the torch and the base material. However, with plasma spraying, the melting point of the raw material used can be sprayed up to about 3500 ° C.

  In general, in the thermal spraying, the powder is adhered on the base material by the anchor effect, so that the powder for thermal spraying is preferably a mass of 5 μm or more, and all the thermal spraying powder in which anatase is transferred to rutile is used. It has been. Anatase crystal form of titanium oxide (titania) has a strong photocatalytic action, but if the photocatalyst particles after spraying all have anatase crystals, the decomposition action is too strong and the substrate is committed. It will not be possible. However, the anatase crystals 10 to 40 can be selected by adjusting the particle size, spraying temperature, substrate surface temperature, and heat source to be used to 5 to 25 μm, about 2900 to 3000 ° C., 40 to 50 ° C., and gas, respectively. % Can be synthesized. That is, if it exceeds about 750 ° C., which is the transformation point between anatase and rutile, all the crystals become rutile crystals, but according to the above-mentioned low temperature spraying method, all the rutile crystal particles are prepared and sprayed. , 10 to 40% of anatase crystals are produced, and the rest are rutile crystals. According to various experiments, it was found as a result of X-ray analysis that the weight ratio of anatase to rutile after spraying is preferably 1: 3.

In addition, since all the anatase crystal form of titanium oxide (TiO ₂ ) has an extremely strong oxidizing power and makes the base material shabby, the weight of anatase and rutile of the titanium oxide particles as raw materials in printing ink or paint The ratio is preferably 20 to 50%: 50 to 80%. When the ratio of anatase is less than this, the photocatalytic action is weak, and when the ratio is more than this, the photocatalytic action is too strong and the binder 6 is decomposed to produce ink or paint. It will be disassembled immediately. In particular, the weight ratio of anatase to rutile is most preferably about 3 to 7.

  The titanium raw material does not necessarily need to be anatase and rutile, and an appropriate photocatalyst can be obtained by adjusting the comparison between anatase with strong catalytic activity and anatase with low catalytic activity.

  In general, the photocatalyst is a non-eluting system, and the metal supported on the optical semiconductor powder acts as an electrode, and it does not dissolve and sterilize in the liquid, but sterilizes by OH-radicals generated in the presence of water. It is effective. In contrast, a conventional elution antibacterial agent, for example, a mixture of an antibacterial agent consisting of zeolite carrying a metal such as antibacterial silver, copper, zinc, etc. and a binder is applied to the required place and dried. As shown in FIG. 3, the metal immediately dissolves in the liquid and exhibits immediate effect, but the effect decreases in a short time, and the part from which the metal is eluted becomes a nest of bacteria and causes harm. Become.

  As shown in FIG. 3, the photocatalytic functional body of the present invention may be inferior to conventional antibacterial agents in terms of immediate effect, but since it is a non-eluting type, it hardly dissolves in the liquid. The effect will last for a long time.

Therefore, conventional antibacterial agents, for example, zeolite fine particles carrying metal ions (Ag, Cu, Zn) having antibacterial action are mixed with photocatalyst particles (TiO ₂ + Ag) and sprayed at a low temperature, If the supported zeolite fine particles are mixed in a binder and used as a printing ink or paint, an antibacterial agent and a bactericidal agent having immediate effect and durability can be obtained.
