Astrea Materials

Astrea Materials' catalyst technology can assist in preserving air quality in closed environments such as emergency rooms, submarines, airplanes or diving chambers. Our air purification technology based in gold nanoparticles is capable of removing carbon monoxide and volatile organic compounds (VOCs) simultaneously at room temperature in presence of humidity. Our product can be easily integrated into existing technologies such as HEPA filters or catalytic burners.

Currently, the industry uses hopcalite for CO removal at room temperaure. However, hopcalite deactivates rapidly in presence of humidity and therefore requires a previous desiccant stage. This additional stage results in a heavier and bulkier system. With ASTREA ́s catalyst, the weight can be reduced dramatically and at the same time increase the duration of the protection from tenths of minutes to hours.

The adverse effects of volatile organic compounds (VOCs) for human health are well known. These have been reported to be toxic and long exposure is potentially teratogen. For this reason, the air purification of indoor environments from VOCs is a major social concern, which remains largely unsolved.
Astrea Materials presents a revolutionary product based in gold catalyst for the elimination of many VOCs such as formaldehyde or toluene in flow conditions at domestic levels. Importantly, our technology does not produce noxious byproducts but converts these VOCs to carbon dioxide and water.
