It has a strong photo catalytic oxidation-reduction capacity, high chemical stability, non-toxic, forbidden band gap of 3.0 ev, being uv (under 380 nm) excited scope. In the effect of sunlight or ultraviolet light , the electronic (e-) on the valence band can be excited transition to the conduction band and brought a corresponding hole (h +) on the valence band. And then h + e- and h2o adsorbed on the surface of tio2 play a role and generate oh, o2-high active group, active oxygen and hydroxyl radical with high oxidation which can make harmful organics, pollutants odor, bacteria etc. Such as formaldehyde, amino methane, benzene, xylene, ammonia, organic tvoc, and so on oxidative decompose into harmless co2 and h2o. Giving full expression to the nano tio2 photo catalyst for antibacterial, sterilization, disinfections, remove pollutants, hydrophilic, and the self-cleaning properties, it is an ideal environmental protection products.
