Photocatalytic Oxidation Technology for Trace Contaminant Control in Aircraft and Spacecraft

A novel approach to vehicle airborne contaminant removal based on UV illumination of the photoactive semiconductor TiO₂ (titania) at room temperature is described. This paper describes fundamental surface chemistry measurements, prototype development, and theoretical models needed for practical application of the technology. The process of incorporating this information into the design of effective air-purifiers for cabin air applications is described.
