The characters of Nanometer
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.
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.
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
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
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.
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
Photocatalyst is a semiconductor that strong oxidation occurs on
When the surface of the XO2 transparent thin film, are exposed by
Electron and positive holes create very strong oxidizers, called
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.
