The photocatalyst has a reaction mechanism in which light (ultraviolet ray) is irradiated on the catalyst surface to generate hydroxide radical ions and radical peroxide radicals, and decomposes the substances adsorbed on the surface of the photocatalyst by their strong oxidizing power. As follows.

However, since these reactions are carried out only under limited conditions in which light, that is, ultraviolet light is present, it is pointed out that the reaction is not formed in a dark room or in the absence of light (light) .

More specifically, the catalyst composition according to the present invention comprises a first metal (A), which is titanium and / or tin, and a second metal (A), which can react with oxygen and water in the air, Group 1 metals and 4-period metals.

The catalyst composition of the present invention activates the reaction of the second metal (B) and the second metal (B) which reduce the band gap energy so that the reaction with oxygen and water becomes active on the surface of titanium (Ti) or Sn (tin) A third metal (C) that acts as a promoter catalyst spurts electrons from the surface into the air and produces holes, which are mixed with the first metal (A), which functions to generate hydroxyl groups and oxygen anions, The oxidation and reduction reactions with oxygen and water are performed to form a hydroxyl group. The thus formed hydroxyl group and oxygen anion decompose harmful components attached to the surface of the catalyst and remove bacteria and fungi to perform a strong antibacterial and sterilizing action .

If the weight ratio of the first metal (A), the second metal (B) and the third metal (C) is out of the above range, the band gap energy of the first metal oxide can not be lowered. The reaction with water may not be performed properly, or the reaction between the first metal and the second metal may not be activated, resulting in degradation of organic materials and sterilization.

If the weight ratio of the third metal to the second metal is less than 0.1, the reaction between the first metal and the second metal can not be activated, and the decomposition of the organic material, the disinfecting power, etc. of the catalyst may be degraded. A side reaction for suppressing the reaction between the first metal and the second metal is generated, so that the decomposition of organic materials and the sterilizing power may be lowered.

If the content of the first metal (A) precursor, the second metal (B) precursor and the third metal (C) precursor is out of the above range, the band gap energy of the first metal oxide can not be lowered. The reaction between water and moisture may not be performed properly, or the reaction between the first metal and the second metal may not be activated, resulting in degradation of organic matter and sterilizing power.

If the weight ratio of the third metal precursor to the second metal precursor is less than 0.1, the reaction between the first metal and the second metal may not be activated, so that the decomposition of the organic material and the sterilizing power of the catalyst may be reduced.

In this case, if the drying temperature is too low or the drying time is too short, the catalyst may not be completely dried to contain the solvent on the surface of the catalyst composition, resulting in deterioration of activity. If the drying temperature is too high or the drying time is too long, May result in degradation of the catalyst composition due to the presence of the catalyst.

If the calcination temperature for the preparation of the catalyst composition is less than 400 ° C, the composite oxide particles and pores of the catalyst composition may be unevenly distributed or the composite metal oxide may not be formed.

The catalyst composition prepared as described above is dispersed in water or alcohol to be coated on a coating object such as a back instrument, a mask, a filter, a wallpaper, ornaments and the like. In order to improve adhesion, the catalyst composition is activated and sterilized, , It is preferable to use an inorganic binder containing SiO ₂ in addition to further mixing a binder in terms of not interfering with the deodorizing action. Specific examples thereof include siloxane bonds (Si-O-Si) on the surface and a large number of hydroxyl groups (OH groups) on the surface thereof.

At this time, the first metal (A) precursor is a metal oxide precursor of a metal selected from the group consisting of titanium, tin and alloys thereof, preferably titanium alkoxide , Tin alkoxide, and mixtures thereof.

The titanium alkoxide and the tin alkoxide are precursors capable of forming metal oxides because alkoxide such as ethoxide, butoxide, isopropoxide and the like is attached to the metal center atom.

The first metal (A) precursor, the second metal (B) precursor and the third metal (C) precursor are mixed in a solvent. The solvent may be any solvent capable of dispersing the first to third metal precursors, and may be water or alcohol. Ethanol, propanol, 2-propanol, butanol and the like may be used as the alcohol .

The content of the solvent is not particularly limited as long as it can sufficiently dissolve and disperse the first to third metal precursors, and preferably the solvent: first to third metal precursors = 100: 1 to 1: 1 It is possible to sufficiently dissolve and disperse the first to third metal precursors without increasing the manufacturing cost.

If the content ratio of the acid and the first to third metal precursors is out of the above range and the content of the acid is high, the pH becomes too low to cause generation of acid sites on the oxide surface of the first metal, Is too low, there is almost no generation of acid sites on the oxide surface of the first metal, so that the sol state can not be maintained smoothly.

The stirring can be carried out by an apparatus and a method which can be practiced by a person skilled in the art and can be carried out by stirring the metal at 60 to 200 rpm for at least 3 hours so that the metal is uniformly added onto the metal oxide have.

In order to improve the adhesion of the catalyst composition thus prepared, a binder may be further mixed and used in view of not interfering with the activity of the catalyst composition and the sterilizing, antibacterial and deodorizing action, and it is possible to use an inorganic binder containing SiO ₂ .

In general, organic or inorganic fungicides, bendiimidazoles, triazoles, phenols, sulfones, imides and derivatives thereof can be used. Specific examples thereof include 2-pyridinethiol-oxide-sodium salts, N, N-phenylsulfimide, diiododimethyl-p-tolylsulfone, and derivative compounds thereof may be used alone or in combination.

The antimicrobial and fungicidal agent is used in an amount of 0.1 to 5% by weight. When the amount is less than 0.1% by weight, the effect of addition is not expected. When the amount is more than 5% by weight, It does not need to be added in excess.

The solvent used for dissolving such components may be water or alcohol in consideration of the solubility of all components contained therein, and preferably water is preferably used. If the amount of the solvent is less than 10% by weight, the solubility is problematic. If the amount of the solvent is more than 30% by weight, the solvent is excessively diluted, which results in inadequate use as an oxidation catalyst composition.
