What exactly is photocatalyst?
In short, the photocatalyst is a process in which a medium decomposes bacteria and bacteria into carbon dioxide and water under the action of light, and this medium is called titanium dioxide.
Titanium dioxide is a strange name. In fact, it is an “old friend” in our life. Whether it is sunscreen used in summer, paint on the wall at home or white in candy, titanium dioxide is an important component.
So, why do we need to add UVA + photocatalyst when UVC antivirus is available in the UV home?
The reason is that the light intensity of UVA is ten times that of UVC. Although it does not have much sterilization effect, it is the best trigger medium for photocatalysts.
Under the triggering of UVA, the efficiency of the photocatalyst is 1550 times that under the triggering of UVC, that is to say, as the first sterilization and disinfection process, when the photocatalyst is used together with UVA, it can efficiently decompose microorganisms into carbon dioxide and water, and then give them to UVC for killing, which can maximize the killing effect of ultraviolet air.
