Photocatalytic principle and application scope of nano-titanium oxide
''''>Environmental purification nanomaterials are also called nanophotocatalytic materials. Photocatalysis refers to the process in which semiconductor materials convert light energy into chemical energy under light irradiation to promote the degradation of organic matter and the reduction of metal ions.

''''>There are two major types of photocatalytic reactions, consciousness uphill reactions (i.e. reactions in which free energy rises), okay? Light energy is converted into chemical energy. The other type is downhill reaction (i.e. reaction in which free energy decreases). This type of reaction is an effective method for waste gas, waste water and solid organic waste and improving the environment.

''''>photolysis of water by electric shock, which really started the research on heterogeneous semiconductor photocatalysis, and set off the development of photocatalysis and The rush to solve the energy crisis marks the beginning of a new era of heterogeneous photocatalysis. Heterogeneous semiconductor photocatalysis has become the most eye-catching and widely applicable new technology because of its ability to completely destroy various organic and inorganic substances in polluted air and wastewater.

''''>Nano-semiconductor particles have much higher photocatalytic activity than conventional semiconductor materials. There are two main reasons: the quantum size effect of nano-semiconductor particles. The conduction band and valence band energy levels change from continuous to discrete, the energy gap becomes wider, the conduction band potential becomes more negative, and the valence band potential becomes more positive. This greatly shortens the time for electrons to diffuse from the body to the surface of nano-semiconductors, greatly reduces the probability of coincidence with holes, and significantly improves the charge separation effect, resulting in a significant increase in photocatalytic activity.

''''>,
''''> and other harmful gases, use the photocatalytic effect of nano-titanium dioxide to oxidize these gases to form nitric acid and sulfuric acid with low vapor pressure. These nitric acids and sulfuric acids can be absorbed by aqueous solutions to achieve purification effects. At the same time, titanium dioxide, as a photocatalyst, combined with adsorbents (such as zeolite activated silica, etc.), can effectively degrade indoor low-concentration harmful gases under weak ultraviolet light irradiation and excitation conditions. Formaldehyde, toluene and other organic matter can Completely catalyzed and decomposed into carbon dioxide and water.
