Generally, antibacterial agents only have a bactericidal effect and cannot decompose toxins The photocatalyst titanium white powder not only reduction of vitality of the bacteria, and can attack the bacterial outer cell membrane penetrating structure, to completely kill bacteria. At the beginning of 1997, Professor Fujishima and others at the University of Tokyo proved that titanium dioxide has the function of decomposing pathogenic bacteria and toxins. Moreover, according to the literature, titanium dioxide Pseudomonas aeruginosa, Escherichia coli, Staphylococcus aureus, salmonella, bacteria and Aspergillus dental sticks and so has a strong bactericidal ability. The laboratory conducts bactericidal experiments on different microorganisms. The data are shown in the table. It can be seen that under the experimental conditions, the killing rate of the products against Bacillus subtilis var. sp., Escherichia coli and Staphylococcus aureus is over 98%. It is proved that nano titanium dioxide sterilization has broad spectrum. The superiority of nano-titanium dioxide is a prerequisite for widespread use, and these properties are mostly related to the high surface activity and large specific surface area. But it also makes it easy to produce its own agglomeration, so that its performance is difficult to fully play. Therefore, in the process of using nano titanium dioxide, the surface physicochemical properties are first changed by surface treatment to improve the applicability of the powder, and at the same time, it is necessary to uniformly disperse and open the agglomerates to exert its antibacterial properties.
