TV backdrop is a concept which introduced from the decoration of public buildings, mainly refers to the side of the main wall in the living room, bedroom which reflects your décor; generally speaking, the placement of television is the visual center inside the house, the most unique place and the visual focus after you enter the door, serves to fill the open area of TV backdrop in your home space, while modifies the TV backdrop area.

 

However, with the improvement of people's living environment quality requirements, TV backdrop not only plays a decorative role, but also be given a more practical function role by changing its material. In recent years, haze tyranny in China, and cause serious harm to human health, and people turn pale at the mention of a haze. In this context, a lot of air purification products mushroomed soaring up. Photocatalytic technology is a very effective way to clean up the air, which is mainly in the context of the presence of the photocatalyst by light to decompose pollutants in the air, thus to purify the air.

 

Because of tungsten trioxide has strong oxidation ability, with its very narrow band gap it can make full use of visible light, and being a good photocatalyst. When the tungsten trioxide photocatalyst is irradiated in the sun or other visible light, electrons are excited into the conduction band, so that the conduction band be of negative charge; however, the valence band will generate the holes of positive charge because the electrons have been excited out, so, a oxidation - reduction system has been formed to play the role of decomposing pollutants. Besides, tungsten trioxide as a photocatalyst has the advantages of non toxic, pollution and so on. Just image that, the side walls will purify the air, so that you will free from the hazards of formaldehyde, haze ect., isn’t it a crazy thing?
