Abstract

The invention discloses a liquid deposition method of stannic oxide. The liquid deposition method comprises the steps of taking an aqueous solution of stannous fluoride as a raw material, adding an additive containing calcium peroxide, and depositing stannic oxide on the hydrophilic surface of a substrate, wherein the additive also serves as an oxidant and a fluoride trapping agent; and calcium peroxide is added, so that a hydrolysis reaction of stannous fluoride is accelerated and controllable, and the fluoride emission is reduced. The liquid deposition method is suitable for quickly and greenly preparing stannic oxide films and stannic oxide micro and nano structures in various patterns.

Description

technical field [0001] The invention relates to the field of preparation of inorganic materials, in particular to a method for liquid-phase deposition of tin dioxide. Background technique [0002] Liquid phase deposition is an important method for preparing oxide thin films. The raw material used in the liquid phase deposition method is an aqueous solution of metal fluorides. Under acidic conditions, the metal fluoride is slowly hydrolyzed, and the corresponding metal oxide film is directly grown on the surface of the hydrophilic substrate placed in the solution. By adding boric acid solution or metal aluminum to the deposition solution as a consuming agent for fluoride ions, one of the hydrolyzed products, the hydrolysis reaction of the metal fluoride can be continued. At present, the liquid phase deposition method has been successfully applied to SiO 2 、TiO 2 , SnO 2 And the preparation of oxide films of Fe, V, Mn, Nb, Zr, Ni, Ta and other metals. In addition, by adj...
