About NCCO Technology

A Patented Technology Developed by a Member of HKUST Entrepreneurship Progam

The research and development team of NCCO discovered that hospitals and industries are only capable of transferring pollutants instead of completely decomposing them. 

In 2003, NCCO's scientific research team successfully developed NCCO (Nano-Confined Catalytic Oxidation) technology and obtained patents in many countries. NCCO can effectively adsorb and decompose pollutants in the air simultaneously, breaking the common practice of using only adsorption materials.









NANO: The catalytic material is a non-poisonous, recyclable mineral material with well-defined nano tunnel.

CONFINED: A granule of catalytic material with 0.4 cm in diameter has around 400 feet of adsorption tunnel

CATALYTIC: The nano tunnel contains a mass of transition metals

OXIDATION: Active oxygen generated from system can oxidize air pollutants into water vapour and carbon dioxide.

1. Collect air pollutants into nano tunnel, then oxidise and decompose air pollutants into harmless water vapour and carbon dioxide.


2. Exhaust harmless substances to create room for further absorption. The Reactor life spans of 3-5 years. No interim replacement of the reactor is necessary. Disposal of Reactor does not cause any pollution.

Tested by authoritative testing companies, out NCCO technology has an extremely high removal rate of gaseous pollutants, and has excellent sterilization and deodorization effects for Staphylococcus aureus, H3N2 virus, etc.

Unlike traditional air purification which causes secondary pollution, NCCO decomposes air pollutants into water vapour and carbon dioxide and leaves no harm to the environment.

Advantages of NCCO

Compared with most air purification technologies on the market, such as activated carbon, photocatalyst, negative ions, etc., NCCO technology's effectiveness is significantly better. Take activated carbon as an example. It can only adsorb pollutants in a short period, but cannot decompose pollutants. Moreover, when the activated carbon is saturated, the adsorbed contaminants will be rereleased into the air, causing secondary pollution and causing great harm to users' health.


On the contrary, NCCO oxygen polymerization can continuously absorb and decompose harmful pollutants. The life of the NCCO filter can last as long as 12 years in the laboratory environment.

NCCO technology has solved various issues in different fields such as commercial, industrial, retail and automobile. It can deal with various problems with indoor and outdoor air pollution, such as handling public toilets, subway toilets, garbage landfills, and other strong odors. In Hong Kong, NCCO products have been applied to government departments, subways, banks, hospitals, schools, high-end hotels, real estate, and shopping malls.
