In recent years, the importance of indoor air quality (IAQ) in indoor space has been emerging as a new environmental issue both domestically and internationally. The indoor space is limited and occupies more than 80% of human life, but it has limitations on environmental regulation and perception. Indoor air is contaminated by various volatile organic compounds (VOCs) generated by building materials and artificial equipments used in construction by remodeling of new buildings or old buildings and paint. , And the concentration of such polluted air is rapidly increasing as the air circulates continuously.

As an alternative, periodic ventilation is also important, but more active methods such as elimination, substitution, or improvement of sources are required.

In general, a photocatalytic composition having the removal of harmful substances using light and an antibacterial effect and a variety of products containing such a photocatalytic composition have been actively studied more than ever. 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.

Photocatalytic Coating Composition Containing Photocatalytic Coating Agent [Korean Patent No. 0609393] and Photocatalytic Composition for Antibacterial Purification Activity and Screening Screen Coated with the Antibacterial Purification Activity [Korean Patent Publication No. 0395264 There are many other research examples.

However, these catalysts have been pointed out as a disadvantage that the reaction is performed only under a limited condition in which light, that is, ultraviolet light, is not formed in a dark room or where no light (light) is present, and the effect of the catalyst can not be obtained.

The oxygen reaction catalyst composition of the present invention is characterized in that the second metal (B) reduces the band gap energy so that the reaction with oxygen and water is activated on the surface of titanium (Ti) or Sn (tin) (C) that acts as a promoter to protrude electrons from the surface into the air and generate holes, which are mixed with the first metal (A), which functions to generate hydroxyl groups and oxygen anions, By carrying out oxidation and reduction reactions with existing oxygen and water, hydroxyl groups are formed. The formed hydroxyl groups and oxygen anions decompose the harmful components adhering to the catalyst surface and remove bacteria and fungus, .

The weight ratio of the first metal (A), the second metal (B) and the third metal (C) is 100: 1 And the weight ratio of the second metal (B) and the third metal (C) is 10: 1 to 1:10.

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 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 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.

The oxygen-catalyzed catalyst composition according to the present invention is excellent not only in the presence of light (light), but also in harmless substances such as matt, dark room without light, deodorization and disinfection effect of interior and exterior walls, building materials, It can be applied to all living spaces such as inside, windowless interior, household goods.

(A) precursors selected from the group consisting of titanium, tin and alloys thereof, yttrium (Y), zirconium (Zr), molybdenum (Mo), and ruthenium (Ru) , At least one second metal (B) precursor selected from the group consisting of cobalt (Co), copper (Cu), germanium (Ge) and selenium (Se) ) Mixing the precursor into a solvent; And (b) adding an acid to the mixture of step (a) and stirring the mixture.

More specifically, the process for preparing an oxygen-containing catalyst composition according to the present invention comprises mixing a first metal (A) precursor, a second metal (B) precursor and a third metal (C) precursor in a solvent, Is added and stirred to prepare a catalyst composition in the form of a sol-gel.

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 second metal (B) precursor is at least one metal chloride, metal nitride or metal hydroxide selected from the group consisting of yttrium (Y), zirconium (Zr), molybdenum (Mo) and ruthenium (Ru) In the case of a compound containing yttrium as the first metal precursor, it may be yttrium chloride or yttrium nitrate. In the case of zirconium, it may be zirconium chloride or zirconium nitrate. In the case of molybdenum, it may be molybdenum chloride, ammonium molybdate, And in the case of ruthenium, it may be ruthenium chloride.

The acid may be at least one selected from the group consisting of nitric acid, hydrochloric acid and phosphoric acid.

The content ratio of the acid to the first to third metal precursors may be a weight ratio of the acid: the first metal (A) precursor, the second metal (B) precursor and the third metal (C) precursor = 10: 1 to 1: have.

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 are ordinarily practicable by those skilled in the art, and the metal can be stirred for more than 3 hours at preferably 20 to 300 DEG C and 60 rpm or more so that the metal is uniformly added onto the metal oxide, More preferably, it can be stirred at 30 to 200 DEG C at 200 to 700 rpm for 3 to 15 hours.

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 . 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. The colloid is widely applicable to various fields due to its bonding properties, heat resistance, It is preferable to use phenylmethylsiloxane, methyltrimethoxysiloxane or the like as the colloidal silica.

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.
