Working principle
The composite photocatalyst foam metal tip nanocomposite technology integrates nano photocatalyst materials and excellent properties of foam nickel, and evenly loads a certain amount of nano TiO2 on the foam nickel substrate. A kind of supported Photocatalytic Functional material has been obtained. Because of its unique three-dimensional network structure, foamed nickel can be used as an excellent photocatalyst carrier, and nano TiO2 loaded on its surface. So far, it is the most widely used photocatalyst. It has broad application prospects in the degradation of organic pollutants in wastewater, removal of harmful inorganic gases and air purification. TiO2 The electronic structure is characterized by a full valence band and an empty conduction band. Electrons can be excited from the valence band to the free electrons formed by the conduction band when the light intensity is greater than the band gap energy (Eg=3.2ev, which is equal to the photon energy of 387.5nm wavelength), and a positive hole is formed in the valence band, forming electron hole pairs.
TiO2 Photocatalytic oxidation is active hydroxyl (OH) and other active oxidizing substances (O-, OOH, H). Two O Two The result of joint action. At TiO2 The surface generated OH group is highly reactive and has higher reaction energy than all kinds of chemical bond energy in organic compounds, plus O-, OOH, H2O2 The synergistic action of active oxidizing substances can rapidly and effectively decompose organic matter.
