To develop a preparation method for size-controlled nanoparticles, we applied a liquid-phase infiltration (LPI) method to the reverse micelle (RM) reaction. The average sizes of the nanoparticles were 4.6 and 2.0 nm for TiO 2 and FeO, respectively. The size distribution was narrow, and particle crystallization was promoted by the nanoscale reaction field. We have also fabricated the TiO 2/Au films with a highly ordered periodic structure by the LPI method using colloidal crystals as a template. The LPI process is conducive to the preparation of advanced nanoceramics with highly ordered structures.
