Abstract
The present application discloses a method for preparing metal oxide nanoparticles, including the following steps: providing an organic reagent with a molecular formula of X—(SO)—Y and a metal oxide nanoparticle sample, in which the metal oxide nanoparticle sample is an aqueous metal oxide nanoparticle; in X—(SO)—Y, X contains polar functional groups; mixing the organic reagent and the metal oxide nanoparticle sample in a liquid medium and adding an alkaline reagent to a mixed solution of the organic reagent and the metal oxide nanoparticle sample to prepare the metal oxide nanoparticles. The method provided in the present application can reduce the surface defect state of metal oxide nanoparticles, thereby improving the stability of metal oxide nanoparticles.
