Basic functions of photocatalyst
Photocatalyst Nano-TiO2 super disinfections power has been verified not only can kill bacteria, virus and fungi, but also can eliminate foul smell. We believe Photocatalyst Nano-TiO2 can help much in the task of preventing SARS strike back. It has been tested with a series of experiences by different authorities and academic bodies, Food Research Center, Universities, etc, and having very good performance. Photocatalyst. Nano-TiO2 can kill Pseudomonas aeruginosa, Influenza virus, MRSA, Tubercle Bacillus, etc. All those bacteria & virus are highly transmitted in our environment, and will cause severe illness to weak & sick persons. Photocatalyst Nano-TiO2 also has been tested can eliminate the toxic and carcinogen gases, like VOC and formaldehyde, etc. It was reported that VOC and formaldehyde emitted after renovation may affect the health of human, especially causing children blood cancer.
GENS Nano-TiO2 Product Functions
1. Sterilizing Effect
Photocatalyst does not only kill bacteria cells, but also decompose the cell itself. The titanium dioxide photocatalyst has been found to be more effective than any other antibacterial agent, because the photocatalytic reaction works even when there are cells covering the surface and while the bacteria are actively propagating. The end toxin produced at the death of cell is also expected to be decomposed by photocatalytic action. Titanium dioxide does not deteriorate and it shows a long-term anti-bacterial effect. Generally speaking, disinfections by titanium dioxide is three times ber than chlorine, and 1.5 times ber than ozone.
2. Deodorizing Effect
On the deodorizing application, the hydroxyl radicals accelerate the breakdown of any Volatile Organic Compounds or VOCs by destroying the molecular bonds. This will help combine the organic gases to form a single molecule that is not harmful to humans thus enhance the air cleaning efficiency. Some of the examples of odor molecules are: Tobacco odor, formaldehyde, nitrogen dioxide, urine and fecal odor, gasoline, and many other hydro carbon molecules in the atmosphere.
Air purifier with Ti02 can prevent smoke and soil, pollen, bacteria, virus and harmful gas as well as seize the free bacteria in the air by filtering percentage of 99.9% with the help of the highly oxidizing effect of photocatalyst (Ti02).
3. Air Purifying Effect
The photocatalytic reactivity of titanium oxides can be applied for the reduction or elimination of polluted compounds in air such as NOx, cigarette smoke, as well as volatile compounds arising from various construction materials. Also, high photocatalytic reactivity can be applied to protect lamp-houses and walls in tunneling, as well as to prevent white tents from becoming sooty and dark. Atmospheric constituents such as chlorofluorocarbons (CFCs) and CFC substitutes, greenhouse gases, and nitrogenous and sulfurous compounds undergo photochemical reactions either directly or indirectly in the presence of sunlight. In a polluted area, these pollutants can eventually be removed.
4. Anti fogging, Self-Cleaning
Most of the exterior walls of buildings become soiled from automotive exhaust fumes, which contain oily components. When the original building materials are coated with a photocatalyst, a protective film of titanium provides the self-cleaning building by becoming antistatic, super oxidative, and hydrophilic. The hydrocarbon from automotive exhaust is oxidized and the dirt on the walls washes away with rainfall, keeping the building exterior clean at all times.
5. Water Purification
Photocatalyst coupled with UV lights can oxidize organic pollutants into nontoxic materials, such as CO2 and water and can disinfect certain bacteria. This technology is very effective at removing further hazardous organic compounds (TOCs) and at killing a variety of bacteria and some viruses in the secondary wastewater treatment. Pilot projects demonstrated that photocatalytic detoxification systems could effectively kill fecal coli form bacteria in secondary wastewater treatment.
