What's PCO?
Photocatalyst (TiO2) is a semiconductor that has strong oxidation. Shining of light source can stir up oxidation-reduction reaction on its surface, and the surface will release free radicals （•OH） and （•O ）, at the moment, chain degradation reaction occurs between the free radicals and kinds of contaminant and bacteria each other. And the reaction can realize the functions of air purification, anti-bacteria, anti-dirtiness and deodorization, hydrophilic nature, and so on.
Utilized in air purification, it can efficiently decompose and eliminate many kinds of organic and inorganic materials and gases in the air.
Coated on nickel foam filter, it is efficient for long consumed without declining with the time, and very convenient for maintenance--the TiO2 nickel foam filter can be washed without any destruction of its efficiency.
