THIS NATIONAL RENEWABLE ENERGY LABORATORY- DESIGNED PHOTOCATALYTIC AIR CLEANER IS MEAnT TO CLEAN THE CABIN AIR IN AUTOMOBILES OF VOLATILE ORGANIC COMPOUNDS ( VOCS) AND BIOAEROSOLS (VIRUS, BACTERIAL,ETC). The principal of operation entails the following: cabin air passes through this device and VOCs and/or bioaerosols are absorbed onto the surfaces of a packing media which is coated with titanium dioxide. The titanium dioxide compounds on its surface when illuminated with near UV light (having a wavelength of 300 - 365nm) the absorbed compounds are typically oxidized with CO2 and water.

Image title | This NREL-designed photocatalytic air cleaner is meant to clean the cabin air in automobiles of volatile organic compounds (VOCs) and bioaerosols (virus, bacterial, etc.). The principal of operation entails the following: cabin air passes through this device and VOCs and/or bioaerosols are adsorbed onto the surface of a packing media which is coated with titanium dioxide. The titanium dioxide is a photocatalytic material that oxidizes compounds on its surface when illuminated with near UV light (having a wavelength of 300 - 365 nm). The adsorbed compounds are typically oxidized with CO2 and water. |
