  • Photocatalytic Fog Disseminating System for Purifying Air and Surfaces
    Publication number: 20090297399
    Abstract: A photocatalytic fog disseminating system is used to disperse and activate photocatalytic particles. The photocatalytic particles preferably are nanoscale particles of titanium oxide. An aqueous suspension of the photocatalytic particles is dispersed by the system as an aerosol, and a photon source is used to excite the dispersed particles in order to initiate photocatalytic redox reactions that degrade airborne or sedentary organic impurities that come into contact with the aerosol.
