The present invention provides a liquid phase synthesis method capable of producing metal oxide nanoparticles having a particle size of 1 × 10 −8 m or less, excellent crystallinity, and capable of being stably dispersed in an organic solvent for dispersion with high productivity. To do. A method for producing metal oxide nanoparticles includes: (A) preparing a reaction solution by mixing a metal alkoxide, a surfactant, and a first organic solvent under an inert atmosphere; The reaction initiator prepared by mixing the catalyst and the solvent and the reaction solution are mixed and heated under an inert atmosphere to produce an intermediate product. (C) the intermediate product and the second organic Mixing the solvent, and then heating the mixture of the intermediate product and the second organic solvent under an inert atmosphere, thereby obtaining metal oxide nanoparticles having a surface coated with a surfactant. To do. [Selection] Figure 1 |
