Structural and optical properties of layered ammonium-iron (II) phosphate monohydrate
Ammonium-iron phosphates phases have recently attracted more interest due to their promising applications as fertilizer [1] or as promising anode material for lithium-ion battery application [2], for example. In this context, NH4FePO4·H2O materials are obtained from FeCl2, Fe2O3 and NH4H2PO4 as star...

| 520 | 3 | |a Ammonium-iron phosphates phases have recently attracted more interest due to their promising applications as fertilizer [1] or as promising anode material for lithium-ion battery application [2], for example. In this context, NH4FePO4·H2O materials are obtained from FeCl2, Fe2O3 and NH4H2PO4 as starting reagents and NH4OH solution by one step hydrothermal method. The factors that affect the formation processes and the product morphologies: the pH and reaction time have been analysed. The as-synthesized compounds have been characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and Fourier Transform infrared (FT-IR) spectroscopy. The optical properties of NH4FePO4·H2O were for the first time studied in this research work: the material displays ptype conductivity behaviour and the value for direct optical band gap EG is estimated to be approximately ~3.6 eV. The results from this paper suggests that these phosphate materials could be suitable candidates for several applications as for example in photovoltaic technology. | |
