What is Titanium Dioxide Photocatalyst ?
Titanium Dioxide is one of the basic materials in everyday life. It has been widely used as white pigment in paints, cosmetics and foodstuffs. When nano sized Titanium Dioxide is exposed to UV or visible light in the presence of water vapor, two highly reactive substances are formed: hydroxyl radicals [OH] and a superoxide ion [O2-1]. These are highly reactive chemical species can decompose volatile organic compounds, odor, formaldehyde, bacteria into harmless substance like Carbon Dioxide and water.







Exposure to light energy
When a photon (light) with an suitable energy excites an electron (e-) from the valence band to the conduction band and leaving a positive hole (h+) behind.

OH radical appearance
The positive holes have the strong oxidation power and can react in an one-electron oxidation step with water to produce the highly reactive hydroxyl radical (•OH). Both the holes and the hydroxyl radicals are very powerful oxidants, which can be used to oxidize most organic contaminants.

Decomposition of organic compound
hydroxyl radical (•OH) takes the electron by the strong oxidation from the nearby organic compound to become stable oneself. In this way the organic compound is decomposed by loss of the electron and finally becomes carbon dioxide and water

RoHS Directive 2002/95/EC Hazardous Substances Test
E-coli & S. aureus Removal Test

Specimen preparation
1. 20 ml ITP catalyst was inoculated with 0.1 ml bacteria culture (107 cells/ml)
2. 20ml 0.85% saline was inoculated with 0.1mL bacteria culture as a control
3. Place the ITP catalyst mixture in a light intensity of 850 ±50 lux
4. Pipette 1ml of catalyst mixtures at the time interval of 10 seconds, 1 min, 5 min,
5. 10 min, 30 min, 60 min and 24-hr for conducting standard plate count;
6. The plates were incubated at 35℃ for 48-hr;
7. Plate count agar was used for the bacteria count.

 * Whenever there is no bacterium was detected on agar plate, the laboratory will report the result as less than one
** TNTC = Too numerous to count
Total Bacteria Surface Swab Test

Sampling procedure
1. Pick up a sterile, non-cotton swab from the package
2. Moisten the swab with sterile phosphate-buffered saline (PBS) solution
3. Wipe the surface. The wipe area is 10cm X 10cm.
4. Place the sampled swab in a sterile conical vial
5. Submit the samples to the laboratory for analysis
Formaldehyde Removal Test

Specimen preparation
1. Dosage of 20g/m2 ITP catalyst was used to spray coated on 6 pieces of 1m×1m card board specimen
2. 3 Specimens was put into a control chamber and 3 specimens were put into a test chamber.  Each chamber is 1.5m3 in volume
3. 40w fluorescent light was used in each chamber as light source
4. Fix amount of Formaldehyde was injected into each chamber
5. Measurements were taken after 24hr

Formaldehyde concentration reduced from 2.62mg/m3 to 0.55mg/m3 in 24 hours.
The ITP catalyst reduced 80% of the formaldehyde in 24 hours.
Decomposition of Methylene Blue

Specimen preparation
1. Dosage of 20g/m2 ITP catalyst was used to spray coated on a wallpaper specimen
2. Dosage of 60ml/m2 10 ppm Methylene blue was coated onto the top of cured ITP catalyst surface

1. Place the container under a fluorescent tube of 4000lux
2. Observe the color change after 12 hours

Methylene Blue has been decomposed completely after 12 hours irradiation with fluorescent light.
