Iron(III) oxide nanoparticles in the thermally induced oxidative decomposition of Prussian Blue, Fe-4[Fe(CN)(6)](3)

Original language description

The thermally induced decomposition of Prussian Blue, Fe-4[Fe(CN)(6)](3) (PB), was studied in air at 250 and 350 C. Amorphous Fe2O3 nanoparticles, cubic bixbyite beta- and cubic spinel gamma-Fe2O3 (maghemite) polymorphs, have been identified as the products of the decomposition under different reaction conditions. Fe-57 Mossbauer spectroscopy, XRD, AFM, TEM, quasielastic light scattering method (QELS) of particle size analysis, BET surface area, and magnetization measurements were used to understand theinfluence of the PB particle size and oxidation conditions on the decomposition mechanism at 250 and 350 C. At a minimum decomposition temperature of 250 degreesC, amorphous Fe2O3 nanoparticles were formed with the size ranging from 1 to 4 nm and largesurface area of 400-200 m(2)/g in dependence on the PB particle size. Such small amorphous Fe2O3 nanoparticles were obtained by the solid-state route for the first time. At 350 degreesC, cubic beta-Fe2O3 and gamma-Fe2O3 polymorphs were id
