Preparation of Nanoparticulate ErFeO₃ by Microwave Assisted Process and its Photocatalytic Activity

Abstract:

Using Er (NO₃)₃·5H₂O and Fe (NO₃)₃·9H₂O as major materials, the ErFeO₃nanoparticles were prepared by successive microwave processing and high temperature calcination. The samples were characterized by thermogravimetric and differential thermal analysis (TG-DTA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and UV-visible diffuse reflectance spectroscopy (DRS). It was found that the single phase ErFeO₃ can be obtained through the calcination of microwave processed ErFeO₃ precursors at 800°C, and the resulting product was approximation flake of 20-80 nm. The visible-light photocatalytic activity of ErFeO₃nanoparticles was investigated in experimental simulation wastewater containing 10 mg/L methyl orange (MO). The results show that ErFeO₃nanoparticles appear high photocatalytic activity for the decomposition of MO under visible-light irradiation.
