The present invention relates to a method for preparing nanoparticles, and more particularly, by preparing a composite of metal nanoparticles and inorganic oxide nanoparticles according to a sol-gel process by using a branched polymer as a reducing agent, the complex is a separate reducing agent. Or do not need a stabilizer, can be prepared at room temperature, atmospheric pressure, can control the size and shape of the nanoparticles as desired, to provide a composite having excellent characteristics such as long-term dispersion stability, small size, narrow size distribution, etc. Can be. |
