High Quality Monodispersed Oxide Nanoparticles Prepared by the Liquid Phase Deposition Method in Aqueous Polymer Solution

Abstract

Monodispersed TiO2 nanoparticles were synthesized by the LPD process using polymer aqueous solution of polyethyleneglycol (PEG) in order to control reactivity of metal-fluoro complex and size of deposited TiO2 particles. Monodispersed well- crystallized anatase particles are found after several minutes and easily separated from the reaction solution. The particle size of obtained samples ranged from ca. 3-5 nm with around 10% of standard deviation values. The synthesizing method presents a new route for preparing well-crystallized metal oxide nanopartcles with potential applications at an ambient condition.
