technical field

Background technique

Nano-photocatalysts are the nemesis of pollutants, and their mechanism of action is simply that: nano-photocatalysts are excited to generate "electron-hole" pairs (a kind of high-energy particles) under the irradiation of specific wavelengths of light. After this "electron-hole" pair interacts with the surrounding water and oxygen, it has a strong oxidation-reduction ability, which can directly decompose formaldehyde, benzene and other pollutants in the air into harmless and odorless substances, and destroy The cell wall of bacteria kills bacteria and decomposes its silk mesh, thus achieving the purpose of eliminating air pollution.

Specifically, under illumination, if the energy of the photon is greater than the forbidden band width of the semiconductor, the electrons (e-) in the valence band will be excited to the conduction band, and holes (h+) will be generated in the valence band at the same time.
