En.HuntKey is the leading supplier of the different kinds of air purifiers. Photocatalyst Air Purifier is one of them. In this blog, we are discussing the work process of the air purifiers:
What about photocatalysts? When you see "photo" attached to a word, you can be pretty sure light is engaged: phōtos is the Greek word for "light." Photocatalysis means light is interested in making a catalyst do its job. In simple terms, light gives the energy that allows the catalyst to work.
Photocatalytic air purifiers clean the air is typically titanium dioxide, and it's powered by ultraviolet (UV) light. UV has the short-wavelength light just beyond the blue/violet part of the electromagnetic spectrum that human eyes can see. One of the best part is that it has much more energy than ordinary, visible light—and precisely the correct amount of energy to get titanium dioxide excited.
Titanium dioxide is a semiconductor. You don't need much titanium dioxide: just a thin film covering the surface of a backing material called a substrate, which are normally made from a ceramic or a piece of metal.
Here, then, is the significant advantage that photocatalytic air purifiers have over other air-cleaning technologies, such as filters. Instead of simply trapping pollutants, they transform the harmful chemicals and efficiently destroy them.
