Research Status of ATO Nano Powder

2018-09-27

The antimony tin oxide (ATO) nanopowder is a nano-powder with good crystallinity obtained by substitution of Sb element in the SnO2 lattice to form a substitutional solid solution. The hetero-Sb makes the surface morphology of the hybrid electron-selective layer more dense and improved, thereby improving the electrical conductivity of the ATO nano-powder. ATO nanomaterials are a new type of conductive material with electrochromic properties, high electrical conductivity and good light transmittance.
 
Method for preparing ATO nano powder
At present, ATO nano powder is a novel transparent conductive composite nano material, especially with transparent conductivity, weather resistance and heat insulation. It also has broad development potential and development prospects in the fields of antistatic plastics and infrared absorption. There are three main preparation methods for ATO nano-powders, including solid phase method, liquid phase method and gas phase method.
 
 Application Status of ATO Nano Powder
(1) ATO nano-powder has good crystallinity and infrared absorption. With ATO nanoparticles as a stable dispersion, not only nano-insulating glass coatings can be prepared to block infrared rays, but also can be used to prepare good optical and mechanical properties. Near-infrared interception of organic/inorganic hybrid silica nanocomposite coatings . At present, ATO coating can be prepared by spray pyrolysis technology to prepare tin oxide and antimony doped tin oxide film onto a glass substrate. This ATO coating not only absorbs near-infrared radiation, but also effectively prevents heat conduction and heat. diffusion.
(2) Adding a small amount of ATO nanopowder to plastics, fibers and coatings can make it have antistatic function and can be widely used in daily life.
(3) ATO nano-powder has super-hydrophobic surface and thermal insulation properties, and its application fields are very extensive.
(4) ATO nanomaterials have excellent catalytic properties and can be used to treat wastewater, showing better superiority.
(5) ATO nanomaterials have good photovoltaic performance because the doping of Sb in SnO2 makes the surface morphology of the hybrid electron-selective layer more dense and improved. This improvement is attributed to the high electrical conductivity of the ATO nanoparticles and the good light transmission through the wide band gap of tin oxide, which improves the photovoltaic performance on the basis of SnO2.
