The anti-bacterial effects of nanometer titanium dioxide

In the photocatalytic degradation of bacteria, nanometer titanium dioxide is used to create an antibacterial effect. Nano-titanium dioxide’s electronic structure is characterised by an electronic band with a tio2-filled and empty conduction bands. It can be used in photocatalytic decomposition of bacteria to achieve antibacterial effect. Electronic can be moved from the valence bands to the conduction, and at the same moment the holes in that valence area, which are responsible for generating electronic holes, is also generated by the electric field. A series reaction occurs: adsorption or superoxide anion free radicals reactions with almost all organic matter, including oxygen. The hole can also react to organic matter in bacteria and produce H2O and CO2. This hole converts the OH and H2O that are adsorbed to TiO2 onto *OH. Strong oxidation power, *OH attacks unsaturated organic bonds or extracts H-atoms to produce new free radicals.

Nano titanium dioxide exhibits antibacterial qualities

The antibacterial qualities of nano titanium dioxide are: non-toxic and safe for human skin; Antibacterial strength, wide range; Low odor; Easy to clean; Washable, long shelf life; Very fast action. Silver antibacterial agents require about 24 hours. Antibacterial agents such as nano titanium dioxide are able to maintain their antibacterial effects for life. This antibacterial agent is food-safe and doesn’t cause skin irritation.
