Application Production of Nanometer Material

1.           Overview

1)    The characters of    Nanometer material

When the fineness of substance is as fine as nanometer (10-9 m), the number of atoms included in this every substance syntax will  decrease as the decrease of the dimension of this material. The physical and chemical characters of this material will be much different too compared with normal material with same elements.

        a) The quantum effect is very obvious, and there are many new optical, electricity, and magnetism characters in this substance. 

        b) There are large increase in the specific surface area , so the adsorptivity is very strong.

        c) The chemical activity is strengthen , and there is strong catalysis.

 

2)    Nanometer DiOxide:

Nanometre anatase phase XO2 can be used in purification of air, light catalysis, water-treatment, bacterium resistance and so on Furthermore, it can also be widely used in synthetic fiber, plastics, rubber, ceramic, printing and so on to improve and change their property.

 

Nanometer  DiOxide

 

The capability of producing powerful oxidizing hydroxyl radicals enables photocatalyst (XO2) to be anti-bacterial, non-toxic, deodorizing, hydrophilic, and self-cleaning. These properties make photocatalyst an ideal environmental protection product.

Photocatalyst ( Dioxide or XO2) is a type of catalyst. It can lower the chemical activation energy to enhance chemical reaction or accelerate the reaction rate. However, the catalyst itself will not undergo changes and its structure will not be damaged as a result of the chemical reaction.

When  Dioxide (XO2) absorbs Ultraviolet (UV) radiation from sunlight or illuminated light sources, it will produce pairs of electrons and holes (electron-hole pairs), which are mobile charge carriers carrying negative and positive charge respectively. The hole has strong oxidizing power and the electron has strong reducing power. When these electron-hole pairs react with moisture on the surface of the  Dioxide (XO2), powerful oxidizing hydroxyl radicals like 0, 02, 01-i etc. will be produced.

These hydroxyl radicals can provide different treatments to treat bacteria (organic matters) and odour (organic gases) specifically. The very strong oxidizing power of  Dioxide can destroy bacteria’s coil rriemhrane, causing leakage of the cytoplasm which results in the death of bacteria, coagulate the virus protein and inhibit its activity, capture and kill the bacteria that suspended in the air. Air passing through  Dioxide purifier will be 99.9970/0 bacteria-free-

Approved by the food testing laboratory of the United States Food and Drug Administration (FDA),  XO2 Dioxide is considered a safe substance and harmless to human. It is commonly used in foodstuffs, domestic  commodities, cosmetics and cultivation. After illuminated by light,  dioxide will produce hydroxyl radicals, which react with the organic matters in the air to  form non-toxic inorganic matters. On the deodorizing application, the hydroxyl radicals will destroy the energy bonds of the organic gaseous molecules. This will help combine the organic gases to form a single molecule and accelerate the breakdown of organic gaseous substances, thus enhance the air cleaning efficiency.

Dioxide, also known as ‘photocatalyst’, has oxidizing power stronger than ozone ion, and absorbing power better than HPEA activated carbon. According to trials performed by European and United States authoritative laboratories, the deodorizing power of a square centimetre (cm2) of photocatalyst is equivalent to about 500 refrigerator activated carbon deodorants and 150 times stronger than the high performance activated carbon. And, more importantly, it produces no secondary public nuisance.

Specially treated  Dioxide (XO2) can he sprayed on window to form a thin film that is antifogging and heat tolerable up to 400 degree Celsius. It is also water stainless due to its hydrophilic nature. When dust particles fail on a  dioxide treated surface, it can be removed by clean water. The hydrophilic nature of  dioxide, coupled with the gravity, will enable the dust particles to be swept away following the water stream, thus making the product self-cleaning.

Nowadays, we live in enclosed compartments for a long time. According to proven statistics, there are more than 5,000 types of carcinogens hidden in enclosed compartments, which the air-conditioning system we currently use is not able to break down. Compared with various treatment methods, photocatalyst is the most ideal one, completely removing mites in the air, which causes go0!0 of asthmatic allergy cases.

Today; there are a lot of available products in the market that claim to have capability of killing bacteria and breaking down organic gases that cause damages to our health. However, photocatalyst, as a product of the world’s most advanced environmental technology, is the most effective solution in resolving health problems caused by human damaging chemical substances, allergens and harmful bacteria.

Nano  Dioxide as photocatalyst As an example of the application, nano—structured  dioxide is now used in bathing ceramic as photocatalyst.

Photocatalyst is a semiconductor that strong oxidation occurs on the surface by the UV Tight exposure. And the organic compounds, bacteria which sticks to it’ s surface can be removed with this oxidation power.

When the surface of the XO2 transparent thin film, are exposed by the Uv lights, negatively charged particles : electrons & :are released, just as the same way as the electron released when sunlight hits the surface of the silicon solar power cells. Simultaneously, positively charged holes are formed on the surface of the thin film at the mark that a electron released.

Electron and positive holes create very strong oxidizers, called the hydroxide radical, even stronger than the chlorine used as a sterilizer, hypochlorous acid, and ozone, When harmful substances stick to the positive holes, they are completely broken down into the carbon dioxide and other harmless compounds. The hydroxide radical also can inhibit the growth of bacteria and mold.

white itself is a substance with Chemical inertness has no poison, no  hazard, no chemical reaction with acid and alkali under ordinary conditions, and has good compatibility with human body. On the contrary, anatase nanometer can strongly absorb ultraviolet light and partial visual light in sunshine, stimulate aperture-electric pair on the Sun’s surface, and release strong photon simultaneously. The energy of this photon is about 3600k which roughly equates to the temperature on the suns surface and this enables it to kill various virus and decompound organics.

Therefore nanometer white is basic substance for preparation of different sorts of photocatalyst and is broadly used in environmental protection, plastic, ceramic and other fields. When used in cosmetic, anatase nanometer white has a very good reputation as “Not tanned in sunshine, while in environmental protection, it surely will revolutionize the technology in the field, just because it can completely decompound every organics by the direct use of sunlight as energy arid without causing any new pollutions.
