For example, the ultra-thin Bi₂Se₃ nanomaterials have a rich charge transfer surface and can be used as an electronic platform to penetrate into the interior of the material, greatly reducing the charge transfer resistance and improving the overall conductivity. The rich interface between the two selenides promotes Na + migration and provides additional active sites; Thermoelectric materials: Bi₂Se₃ has certain thermoelectric properties, which can convert heat energy into electric energy, and has application potential in thermoelectric generators. Electronics and devices: Due to their special electronic properties, they can be used in the development of new electronic devices, such as topological insulator transistors and topological insulator spintronics devices, which have potential applications in quantum computing and quantum information processing; Photoelectric devices: can exhibit two-dimensional electrical properties in thin layer form, and their unique crystal and electronic structure has broadband light absorption, thickness dependent surface band gap and polarization sensitive light response characteristics, which are suitable for optoelectronics fields, such as vision-infrared detection, terahertz detection, etc. Applications related to magnetoelectric properties: exhibits magnetoelectric properties, that is, a voltage is generated in a magnetic field, or its magnetism can be changed when a voltage is applied, which makes it a potential application in the development of magnetoelectric sensors and memory devices; Photothermal\/photodynamic combined therapy: If prepared into Bi₂Se�3@AIPH nanoparticles, under single near-infrared light irradiation, photothermal therapy and oxygen-independent photodynamic therapy and immunotherapy can be used to treat hypoxic tumors; Catalyst: Bi-₂ Se₃ loaded on the TiO₂ to obtain a nanocomposite, which not only improves the effective separation ability of the TiO₂ carrier, but also enhances the visible light absorption rate of the TiO₂, showing excellent degradation activity and stability to polybutyl acrylate and butyl butoxypropioate.
