Abstract

The synthesis method for a monodispersed rod nano SnO2 monocrystal with tetragonal structure of 5-50nm size and 50-300 length comprises: dissolving the SnCl4 into HCl to mix and then put into high-pressure kettle, filling air to 0.1-1.5MPa for pre-pressing; holding for 4-8h at 200-400Deg. This invention makes use of solution acidity and pre-pressing to grow the mono crystal with largest density and almost no detect fit to cell cathode material or luminous device.

Description

technical field

[0001] The invention relates to a tetragonal structure SnO 2 Monodisperse nanometer single crystal and its synthesis method, especially related to a tetragonal structure SnO prepared by hydrothermal-hydraulic method 2 Monodisperse nano single crystal and its synthesis method. Background technique

[0002] SnO 2 It is a typical n-type semiconductor material with a wide range of uses. It can be used as a catalyst and chemical raw material in organic synthesis; it can be used as an opacifying agent for glazes and enamel in the ceramic industry; it can also be used for conductive materials and films. Resistors and optoelectronic devices and other fields. Due to the small size effect and surface effect, nano-tin oxide has special photoelectric properties and gas-sensing properties, making it have potential applications in gas-sensing components, semiconductor components, electrode materials, solar cells, etc. Therefore, the application and development of tin o...
