|dc.description.abstract||In summary, supercritical methanol acts not only as the reaction medium but also the reducing agent, in synthesis of pure metal particles. Thus, Ni particles were synthesized without addition of reducing agent. In addition, phase-controlled synthesis of Ni particles was achieved by changing starting materials. For metal oxides such as CeO2 and ZnO, morphology and size of particles were controlled by surface modifiers such as decanoic acid, oleic acid and CTAB. Barium titanate, one of important ferroelectric nanoparticles was synthesized in supercritical water, and it was observed that reaction time and molar ratio of barium hydroxide to anatase affect conversion of anatase. Adding KOH achieved the BaTiO3 nanoparticles with the high purity. Hydrothermal/solvothermal method using supercritical fluid provides effective process to synthesize metal/metal oxide nanoparticles. As mentioned previously, process using supercritical fluid need short reaction time and can eco-friendly process.||-|
