VOC Removal Air Purification Service

**CT Catalyst is a nano-material introduced from Japan, which can manage air pollution problem. It is able to control the VOCs, deodorise, anti-bacteria and anti-mold. Certified to be safe, non-toxic and not irritant.**

Chemical Name: CHARGE TRANSFER TYPE CATALYST (Short Form: CT Catalyst)
(JPO Patent No.: 3514702 2004.1.23 , IPD Patent Ref: HK1116125)

Introduction
CT catalyst particles are as fine as 300nm diameter in average. By using CT Spray Coating Technique (with 1-5μm diameter spray head), CT catalyst particles are evenly distributed on the surface of furniture, walls and every drawer as well. It allows the CT catalyst particles to fully perform in oxidation and reduction so as to eliminate the VOCs inside the flat rapidly.

Technology Used
CT Catalyst undergoes oxidation or reduction by using catalyst and materials containing charge-transfer-type catalyst.

Oxidation and Reduction
ACID –COOH + O2 (+ e) → CO2 + H2O
ALKALINE –(OH) + H+ → 2H2O (+ e)

Functions
1. Elimination of VOCs & Deodorization (For renovated units)
There are various standards of IAQ among regions and districts. Briefly, the standard of TVOC level is not more than 0.8mg/m3 or 1ppm. In the following table section 1, you may find various IAQ index for reference.
A "CT catalyst ability experiment" has been conducted in a renovated flat. An outstanding result has been recorded (table section 2):

• CT catalyst is able to decompose TVOC more than 90% within just 72 hours.

• In the meantime, the concentration of formaldehyde has reduced 99.4%. Comparing to natural decomposition which needs 3-10 years, CT catalyst is therefore significantly proved to be a strong VOCs killer.

2. Anti Bacteria (For public area, e.g. offices, schools, kindergartens, elderly home)
Japan Food Research Laboratories has tested the anti-bacteria ability of CT catalyst in a 24 hours sample testing.
It conclusively confirms that CT catalyst is able to control the growth of Staphylococcus Aureus, MRSA and Escherichia Coli within a day, in short, bacteria will be eliminated.
CT Catalyst affects the charge balance inside bacterial cells through charge transfer, making the environment impossible for bacterial growth.

3. Anti-mold (For humid flats)
Regarding the anti-mold performance of CT catalyst, a controlled experiment is carried out.
The report indicated that CT catalyst is able to stop the growth of mold, as the testing sample with CT catalyst remind mold-free. It is because CT catalyst is strong in water repellency that separates moisture from the surface.
