Method for preparing tin oxide nanoparticles dispersed in alcohol solvent, and use thereof

Abstract

The present invention relates to the technical field of nano-materials and provides a method for preparing tin oxide (SnO2) nanoparticles dispersed in an alcohol solvent, and use thereof. The preparation method includes: (1) dissolving tin chloride and a base in an ethanol solution, reacting with heating at a constant temperature, subjecting the reaction product to solid-liquid separation, collecting the solid phase, and dissolving the solid phase in an alcohol solvent, to obtain a tin oxide-alcohol dispersion; and (2) adding a quaternary ammonium base to the tin oxide-alcohol dispersion obtained in Step (1), and reacting with stirring, to obtain the tin oxide nanoparticles. The tin oxide nanoparticles of the present invention provide a new approach to the improvement of the stability of optoelectronic devices, and broaden the scope of SnO2 application, thus having important practical significance.
