超臨界水熱法による有機-無機ハイブリッドナノ粒子の合成 Hydrothermal Synthesis of Organic-Inorganic Hybrid Nanoparticles in Supercritical Water
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, CeO<SUB>2</SUB> nanoparticles whose surface was chemically bonded with organic molecules were synthesized. Particle size was about 5nm 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.
