Photocatalyst is not a simple product, it is an industry, a discipline, a scientific field.The noun comes from photocatalyst, also known as photocatalyst. It is a general term for a group of photocatalytic semiconductor materials represented by TiO2, including titanium dioxide (TiO2), zinc oxide (ZnO), tin dioxide (SnO2), zirconium dioxide (ZrO2), cadmium sulfide (CdS) and other oxide sulfide semiconductors.

Different materials of the corresponding wavelength is different also, photocatalytic titanium dioxide (TiO2) is the most commonly used photocatalytic materials, common titanium dioxide (TiO2) need to 388 nm wavelength in the following (uv) light (BeiSenGuang catalyst series products generally choose 185 nm and 284 nm double wavelength of ultraviolet lamp), to the photocatalysis.

Nanoscale (TiO2) properties different from those of ordinary (TiO2) particles, can in the visible light range has very good response effect, high quality TiO2 light catalyst particle...
