Method for preparing stannic oxide by dissolution pyrolysis method

Abstract

The invention discloses a method to prepare tin oxide by dissolving pyrolysis, which comprises: dissolving the tin source and organic acid in reactor at 20-290Deg; stirring and reacting for 0.1-240h to obtain the predecessor; putting the predecessor into muffle furnace for calcining and pyrolysis at temperature more than 280Deg to obtain the product. Wherein, selecting on organic acid arbitrarily from the acetic acid, oxalic acid, citric acid, tartaric acid or aconitic acid; between the dissolution and pyrolysis, using any one of water, alcohol, ethyl ether, acetone or chloroform to clear the predecessor. This invention is simple and low cost, and has high purity.

Description

technical field

[0001] The invention relates to a method for preparing functional materials, in particular to a method for preparing tin oxide by dissolution and pyrolysis. Background technique

[0002] Tin oxide is the most widely used gas-sensing material so far. It has the characteristics of low price, good mechanical, chemical and thermal stability, and fast response speed, and the selectivity to gas can be adjusted by doping different elements. The special pores in the structure of tin oxide can be suitable for the transport of ions in it, so it can be used as an anode material for lithium-ion batteries. Tin oxide is a good catalyst and catalyst carrier. It has a strong complete oxidation ability and has a good effect on the oxidation of organic matter. It can catalyze the fumarate reaction and the oxidation of CO. Tin oxide has excellent optoelectronic properties and can be used to make transparent electrodes, solar energy conversion materials, conductive materials, e...
