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.
