Thermal decomposition of ammonium ferrocyanide, (NH4)4[Fe(CN)6], in air
Original language description
Thermal decomposition of ammonium ferrocyanide, (NH4)4[Fe(CN)6], was investigated by means of thermal analysis and 57Fe Mössbauer spectroscopy. Thermal analysis (TG and DSC) showed multistep decomposition mechanism with the total mass loss of 70% corresponding to complete transformation of the precursor to Fe2O3. Ammonium ferrocyanide was heated in a furnace starting from room temperature up to selected temperature in the range from 60 oC to 350 oC. After the heat treatment up to given temperature, the sample was characterized by room temperature Mössbauer spectroscopy. The decomposition mechanism is based on a sequential formation of (NH4)3[Fe(III)(CN)6], (NH4)3[Fe(II)(CN)5], Fe4(III)[Fe(II)(CN)6]3 (Prussian Blue), and finally Fe2O3. Mössbauer spectroscopy allowed to determine valence states of Fe atoms in the phases unambiguously. Thermal decomposition of ammonium ferrocyanide thus presents a simple method of synthesis of Prussian Blue nanoparticles as well as amorphous Fe2O3 nanoparticles. Amorphous Fe2O3 can be further crystallized to β-Fe2O3, γ-Fe2O3 and/or α-Fe2O3 polymorphs.
