According to one experimental example, experimental results of the same anion emission amount and air purifying ability as the air purification material can be obtained even when titanium dioxide is replaced with aluminum (Al) and rare earth mineral is replaced with boron (B) or doped.

In step S1200, the composition prepared in the quantitative preparation step S1100 is pulverized in a pulverizer maintained at a temperature ranging from 20 to 100 degrees Celsius for 30 minutes to 1 hour by mechanical energy at an acceleration of about 600 m / s2. In the pulverization process (S1200), the alpha phase may be converted into a beta phase and become a mechanical alloy to be semiconducting.

In step S1200, the powdered composition particles of 50 micrometers or less are selectively extracted using a 50 micrometer (um) mesh formed in a multistage manner (S1300).

The powder particles of the selected composition in the sorting process (S1300) may be formed by using a mold capable of forming a first through hole and a plurality of second through holes and forming an outer shape of a circular plate or a rectangular plate as a whole, Ton pressure so as to produce a sample (S1400).

In the forming process (S1400), it is very natural that the sample can be compression-molded into various shapes other than the shape of a circular plate and a rectangular plate.

The compacted composition is subjected to a heat treatment (sintering) (S1500) in a vacuum pressure environment of 1 to minus 5 torr to 1,100 to 1,200 degrees Celsius for 30 minutes to 1 hour in the molding process S1400, .

The compression molded product heat-treated in the sintering process (S1500) is naturally cooled to a temperature of 25 to 60 degrees Celsius at room temperature, heated again at atmospheric pressure at a temperature of 50 to 900 degrees Celsius for 5 to 10 hours, (S1600).

That is, a composition containing Cu - Ni - TiO 2 - Th in a powder state at 20 to 100 ° C was synthesized by mechanical energy while being mechanically alloyed in a semiconducting state while pulverizing a composition prepared in a predetermined amount, The composition powder is compression molded and sintered at a vacuum of 1.0 * 10 -2 to 1.0 * 10 -5 torr and a temperature of 1100 to 1200 ° C for 30 minutes to 1 hour, followed by post-processing at 500 to 900 ° C for 5 to 10 hours Heat treatment is performed to produce an air cleaning material.

When titanium dioxide (Tio2) receives ultraviolet rays from sunlight or fluorescent light, it generates electrons (e) with negative (-) electricity and electrons (h +) with positive (+) electricity similarly to the solar cell shown below Among them, the hole (h +) forms a strong oxidizing hydroxide (OH Radical) and can act as a stronger oxidizing power than chlorine for sterilization or ozone hypochlorous acid.

In addition, the former makes oxygen, which is adsorbed on titanium dioxide, to oxygen ions, which causes the reaction of water with an intermediate of the oxidation reaction and peroxide or hydrogen peroxide.

Such a photocatalytic effect causes contamination prevention, air purification, purification of water, sterilization, deodorization, etc. Titanium dioxide is totally harmless to human body and can be applied as a bowl related to eating habits such as ceramics. It can be applied semi-permanently once applied and its effect can be sustained.

There are various kinds of ions in the air that are very weak, and substances that charge negative are called negative ions, and those that charge positive ions are called positive ions.

Anion is a fine particle of electricity that has a negative charge that charges atoms and atomic molecules. It is also called air vitamins because it has a positive effect on the balance of the autonomic nervous system by acting on the blood and body fluids of the human body.

Titanium dioxide (TiO2), also called titania, is a typical photocatalyst that promotes chemical reactions when light is applied. It is a photocatalyst that was used by American chemist A. Heller between 1965 and 1975 and two Japanese scientists A. Fujishima and K. Honda have been actively investigating the effects of various functions of TiO2 in real life since their efficacy has been experimentally demonstrated.

TiO2 is a functional photocatalyst capable of oxidation, reduction, and hydrophilic reaction in the molecule itself, and has a harmful substance decomposition function, a self-purification function, an antibacterial function, and a sterilizing function.

When TiO2 absorbs ultraviolet light from light, it generates photo-decomposition reaction that decomposes harmful substances, resulting in harmless CO2 and H2O as final reaction products, and these reactions can be used for environmental purification.

In addition, the effect of antibacterial, deodorizing and so on.

Since hydroxy radicals formed after TiO2 absorbs ultraviolet rays have high oxidizing power, they are also very effective for environmental hormones, refractory pollutants, sulfur oxides, nitrogen oxides and volatile contaminants.

In addition, TiO2 has a supershine property, so that, when water droplets touch the surface of TiO2, the water droplets maintain spherical droplets in the form of spherical droplets distorted by surface tension in other materials. It creates a membrane.

That is, when a substance is surrounded by a TiO2 particle layer, even if the surrounding contaminants slowly adhere, it is decomposed and removed naturally, so that dust and dirt are hardly accumulated.

TiO2 has a strong oxidizing power due to the formation of hydroxy radicals generated after absorption of ultraviolet rays from light. It oxidizes and decomposes pathogenic bacteria and bacteria such as E. coli O-157 and Staphylococcus aureus, and acts as antibacterial and sterilizing effect do. In particular, it can be used not only as a toxin of bacteria but also as a deodorizing agent by disinfecting various sanitary devices by breaking down debris.

TiO2 acts as a photocatalyst when the free electrons of TiO2 absorb ultraviolet rays of wavelengths less than 380 nm corresponding to the band gap energy and move up to the conduction band from the valence band, Is generated.

At this time, the electrons react with oxygen to produce superoxide radical (O2-).

e + O2 - > O2-

In addition, the hydroxide ion produces one electron to the hole of the valence band to form hydroxy radical (OH), and the reaction formula is as follows.

OH - - > OH + e-

In particular, the hydroxy radicals generated in this process act as core radicals that enable TiO2 to function as a photocatalyst as a very strong oxidizing agent.

In general, the air around us is dangerously polluted already due to industrialization, increase of vehicles, increase of air-conditioning and heating. Especially, the industrialization of China has taken a steep upward curve, and now it is a reality that it is suffering from fine dust from China as well as yellow dust in spring, and also fine dust warning and warning are made in cold winter.

Fine dust is 10㎛ or less in diameter, and it is a small dust particle that can not be seen by our eyes. It penetrates deeply into human alveoli and causes direct respiratory diseases and lowers immunity. In addition, toxic compounds such as lead, cadmium, and sulfur dioxide contained in fine dusts and heavy metals accumulate in the body, resulting in various fatal diseases.

In particular, research has shown that pregnant women are at risk of premature birth, poor fetal growth, and low cognitive development.

When air pollution such as fine dust concentration gets worse, the measures that have been taken until now are about going out or restricting outdoor exercise.

However, it is almost impossible to abandon all daily life and stay at home only if the air is bad. Work and school are hard to rest, and children who are full of excitement can not be confined to their homes. Also, staying indoors can not guarantee health.

The closed space is not easily circulated or discharged, so it is likely to be contaminated with various fine dusts, noxious gases, fungi, and harmful bacteria. These pollutants can be spread through the respiratory tract or by spreading clothes or body, spreading diseases to the elderly and children.

Therefore, the structure according to the present invention is advantageous in that it can decompose and block harmful substances in the air even when hanging on the neck or putting on clothes, and can go out, outdoor movement, and children's playground activity even when pollution is severe.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art.
