Abstract
The present invention relates to a method for preparing uniform metal oxide nanoparticles. According to the preparation method of the present invention, it is possible to maintain the temperature and pressure inside the reactor in a stable and constant manner by removing water generated in the reaction step for forming metal oxide nanoparticles. Thus, the uniformity of nanoparticles formed is increased, and the reproducibility between batches can be increased even in a repeated process and and a large-scale reaction. Therefore, the preparation method of the present invention can be used to synthesize uniform nanoparticles reproducibly in large quantities.
