Nano- titanium plates photocatalyst applied

High-tech is called a " photocatalyst " in this compelling exhibition is also a focus.

Processed using photocatalyst " photocatalyst ", it fully demonstrated to the people the power of a photocatalyst decontamination cleaning : it not only can be used to decompose water the dirt,surgical implant titanium get rid of the smell , can also be sprayed on the wall and the exterior wall of the building , dust and dirt adhering to resist it for a long period , keep the brand new state.

Photocatalyst is a kind of nanoscale titanium dioxide as the main material , new catalysts occur under light irradiation reactions. According to the developers technician said that this titanium dioxide in the absorption of the sun's ultraviolet rays, the internal electronics will be stimulated to produce strong oxidizing ability, destroy cell membranes , can kill off the air more than 99% of planktonic bacteria. Moreover, it can be restored by an oxidation reaction, the organic matter and harmful gases into harmless water and carbon dioxide and salt , so as to achieve water purification, air purification effect.

Photocatalyst was first proposed by Japanese scientists found that the effect was recognized as early as in 1965 the Japanese scholar tube Takao . Subsequently , the University of Tokyo professor and his students to build a multi- Akira Fujishima in 1972 found irradiating titanium dioxide electrodes , can promote water electrolysis reactions occur , " the multi - Fujishima effect," a sensation. 30 years, a large number of technical personnel in the way of this practical , painstaking research , and finally began a few years ago will be applied to other areas of the vehicle disinfection and antifouling .

The photocatalyst for water purification capacity and ability to decompose on the dirt , it is promising. Patent has been published about the photocatalyst technology , and environmental technology , led to water actually accounted for more than 70%.

Right now , photocatalytic water treatment technology has become a come from behind titanium stockist, but also a variety of medium and small enterprises into the eyes of a fat. They put the maximum financial, material and human resources around the clock to develop new products to grab fat iceberg. According to the Japanese Ministry of the Environment estimates, the market size of the photocatalyst in 2000 although only 25 billion yen ( about 1.65 billion yuan ) , but 2010 will rise to 2 trillion yen (about 132.6 billion yuan ) , and 2020 will surge to 4 trillion yen ( about 265.2 billion yuan ) above.

The 21st century is the century of water . As these banks of Tokyo Bay Water experts predict that cutting-edge technology such as photocatalyst , will lead the new wave of water treatment technology. All kinds of water treatment equipment , will serve as the patron saint of water , constantly out of the lab , off the production line , flying into the homes of ordinary people .
