This paper summarizes specific features of supercritical hydrothermal synthesis: Namely, synthesis of nano single crystals and controllable oxidizing and reducing atmosphere. Synthesis of organic–inorganic hybrid nanoparticles is another unique feature of this method. The synthesized hybrid nanoparticles can be dispersed in organic solvents, from which super lattice structure can be formed.

This paper summarizes specific features of supercritical hydrothermal synthesis of nanoparticles: Nano single crystals of variety of metal or metal oxides can be synthesized. By introducing oxygen or hydrogen gas, oxidizing/reducing atmosphere can be easily controlled. Synthesis of organic–inorganic hybrid nanoparticles by introducing organic ligand is another unique character of this method. The synthesized hybrid nanoparticles can be perfectly dispersed in organic solvents, from which self-assembled super lattice structures can be formed.
