In recent years, with the deep research on semiconductor heterojunction and Z-type mechanism, in order to solve the problem of carbon nitride, scientists usually use other semiconductor materials to form a heterojunction with carbon nitride, for example: carbon nitride / trioxide The tungsten binary heterojunction can expand the spectral range of light absorption by constructing a hybrid system, suppress the recombination of photoelectrons and holes, and obtain higher redox performance.

Ultra-thin diamond saw blade refers to the diamond saw blade with a thickness of less than 1.0 mm and high precision. Its cutting tool slot is narrow, which is beneficial to saving valuable materials in the cutting process. It is widely used in cutting silicon, silicon carbide and other photoelectric materials.

With the sharp rise in oil prices and the depletion of mineral resources, solar energy has attracted more and more attention due to its inexhaustible, unrestricted geographical and clean and safe advantages. Solar cells based on photovoltaic effect to convert solar energy into electricity are one of the main ways to utilize solar energy.

In recent years, semiconductor photocatalysis has become one of the research hotspots in the field of environment. A large number of studies have shown that almost all organic pollutants can be effectively photocatalytically degraded, decolorized and mineralized into inorganic small molecular substances, thereby eliminating environmental pollution and hazards.
