Photocatalyst Window Curtains Photocatalyst curtain is a new kind of environment friendly product, processing photocatalyst coating into production, which has been proved to purify your surrounding air and protect your building interior and exterior from environmental contamination. Function: photocatalyst curtain make use of photocatalyst’ advantages. Photocatalyst(titanium dioxide TiO2) is a safe, non-toxic, anti-oxidant that produces hydroxyl radicals (OH-) that are remarkably effective in rapidly decomposing organic matter, including bacteria, fungi, odors and nicotine. This chemical process of photocatalysis actually converts organic matter into the harmless elements of water and carbon dioxide, which are then released into the air but in such minute quantities that their conversion is unnoticeable. Just using such fuctions, our curtains can absorb and decompose the harmful gases efficiently，such as Formaldehyde(CH2O), Benzene(C6H6), Ammonia(NH3), vaporizing from decoration materials，especially from floor, furniture, wall painting, etc. Beside those, it also can clear up some other air pollutions, such as CO，SO2，NO, and release oxygen anions, returning back us a real green environment. It is so called self-cleaning engineer, which can highly improve our live conditons
