Abstract

We propose a new method to synthesize organic-inorganic hybrid nanoparticles using supercritical hydrothermal synthesis. By introducing organic species, e.g., carboxylic acids, during supercritical hydrothermal synthesis, CeO₂ nanoparticles whose surface was chemically bonded with organic molecules were synthesized. Particle size was about 5 nm and its particle size distribution was very narrow. The hybrid nanoparticles were dispersed perfectly in organic solvent. After the drying of this colloid, we obtained self-assembly structure of nanocrystals.
