PURIFICATION OF AIR INDOOR WITH NANOCRYSTALLINE TITANIUM-DIOXIDE PHOTOCATALYST

摘要

Status quo of indoor air pollution and purification is reviewed in brief. Photocatalysis mechanism and reaction kinetics of nanocrystalline Particles of TiO_2 are presented. The air purification equipment made up of nanocrystalline TiO_2 photocatalylist of honey type and other auxiliary devices is described. Its effect has been tested through eliminating formaldehyde, NO, acetic acid which are the most representatives of air pollutants indoor. The air purification method can eliminate indoor contamination in air rapidly, efficiently and completely and is possible to be widely used.
