CATS: Photocatalysis process helps render some toxic air contaminants harmless

Number 16 in the Clean Air Technologies Series.

With the inhalation of nitrogen oxides (NOx) and volatile organic compounds (VOC) – smog’s two main components – there is risk of asthma attacks being triggered, delicate lung-tissue-damage being caused and bronchitis and pneumonia being contracted.

Now imagine if there was a way to completely rid the air of these harmful air pollutants or, barring this, to facilitate their breakdown or conversion to harmless substances.

Imagine no more.

CristalACTiV™, on its Web site emphasizes it is in the business of manufacturing and commercializing “a wide range of CristalACTiV™ Ultrafine TiO2 [titanium dioxide] that are used in a variety of applications, including technologically advanced systems for environmental pollution control.”

“CristalACTiV™ photocatalysts, added as an active ingredient in paints or in construction materials or directly applied on a variety of substrates, provide de-polluting and self-cleaning functionality to the surfaces treated, rendering them photoactive. Harmful pollutants such as nitrogen oxides (NOx), volatile organic compounds (VOC) or sulfur oxides (SOx) are degraded to harmless substances when they come in contact with the photoactive surfaces,” notes the company on its Web site.

If not a be-all, end-all solution to ridding the world of polluted air, what has been discussed here, nevertheless, seems promising indeed.

  1. Hi Alan,

    The product you are talking about is called KNOxOUT. It is the only paint that uses CristalActive. It will now be available in the US through Environmental Imports, Inc. Please feel free to let me know if you have any questions regarding KNOxOUT.
