Higher catalytic activity. Widely used for indoor air purification.
Higher catalytic activity: the catalytic activity of this style is 30 times higher than that of all nanomaterial titanium dioxide in the market with best catalytic activity by comparing and testing. This style can catch and decompose harmful gases in the room such as formaldehyde and benzene and ammonia. And the product has excellent property of photo catalytic and strong oxidation-reduction capacity in the shine of visible lights and UV lights owing to its small particle size and big surface area, it can completely separate poisonous organic gases such as formaldehyde, hydrocarbons, VOC, toluene into CO2 and H2O.

Picture 2. Corresponding TEM of nano titanium oxide prepared
Picture 3. Degradation curves of Rhoda mine B
As you can see from the picture, titanium oxide prepared has better photo catalytic activity under UV-light, pollutants can be biodegraded completely, but on the same condition, Degussa P25 sold in th e market can only biodegrade about 30 %.
Picture 4. Photos of dispersions of titanium oxide in different concentrations
The concentration of dispersions of titanium oxide prepared is 0.1, 1, 5, 10, 30, 50% separately, which can keep in 48 hours at least. But the dispersion of Degussa P25 whose concentration is 0.1% will precipitate obviously after staying one hour.
