摘要：
Disclosed is a method for producing transition metal oxide fine particles having a size smaller than several micrometers (μm), and more preferably, having a size of several hundred nanometers (nm). To this end, the method for producing transition metal oxide fine particles of the present invention comprises dissolving a transition metal oxide in a strongly basic aqueous solution, and titrating same with a strongly acidic aqueous solution, thereby precipitating transition metal oxide fine particles.
