An in-depth look into our innovative NCCO technology
Our air purification technique involves the use of ‘contained’ ozone in combination with zeolites (crystalline solids with uniformly-sized, nano-scale pores) and other related porous materials. In contrast to ozone generators, which directly release the toxic gas into the environment and are known to be ineffective, NCCO greatly enhances the oxidation of contaminants while avoiding high emission of ozone and harmful reaction intermediates. The zeolites consist of a negatively-charged aluminosilicate framework with loosely bound cations that maintain the charge balance. A number of natural and synthetic zeolites with varying chemical compositions have been exploited for different commercial applications. Zeolite filters can be used in air purification for the adsorption of gaseous pollutants Interestingly, zeolites also have the ability to catalyze diverse reactions inside the nanosized pores . NCCO is based on a catalytic ozonisation mechanism where ozone (O3) provided by an upstream ozone generator is decomposed into molecular oxygen (O2) and active atomic oxygen (O*) at acidic sites of the adsorbent. Gaseous pollutants e.g. VOCs that are adsorbed in the same pore as O* undergo catalytic oxidation within the confined nano-cavity. Previous studies show that reaction intermediates remain in the adsorbent, while the smaller final products (such as carbon dioxide and water) are generally released to regenerate the catalyst. Based on the catalytic process, the life of the NCCO filter has an extremely long functioning and performance life.
Nano is a unit of measure for extremely small objects such as atoms and molecules. 1 nanometre is 1/1,000,000th of the diameter of human hair.
The shape-selective properties of our catalytic material allow their usage in molecular adsorption. A granule of catalytic material with a diameter of 0.4 cm has around 400 feet of adsorption tunnel. This catalytic material is able to absorb certain molecules whilst excluding others. This results in efficient removal of pollutants such as VOCs from the environment.
There are transition metals (Zeolites) impregnated within the porous structure of our catalytic material. These transition metals can act as catalysts to enhance the reaction between the gaseous contaminants and oxidants.
Active oxygen is generated and is able to oxidise gaseous contaminants into non harmful molecules of water and carbon dioxide. These will leave the catalytic material regenerating and releasing more sites to be used for adsorption of pollutants.
