| Research Abstract |
Synthesis procedures for monodipserse particles of metal-hexacyanoferrates, which are also called as Prussian blue and its analogues, have been investigated to achieve precise syntheses of them. Prussian blue is a mixed-valence compound that consists of both Fe(II) and Fe(III) and is thus expected as a kind of functional materials. In this study, separation of the growth step from the nucleation period, which is an essential requirement for monodisperse particle formation, is achieved through constructing reaction systems that are based on three sorts of strategy including generation of the reaction species by reduction reaction, release of the metal ion from its citrate complex, and continuous addition of the reaction solutions from outside of the reaction vessel. Size, shape, and internal structure of monodisperse Prussian blue and its analogues nanoparticles are fairly controlled by the reaction procedures.
