One-Step Preparation of Nanoparticulate TbFeO₃ by Microwave Process and its Visible-Light Photocatalytic Activity

Abstract:

TbFeO₃ nanoparticles were synthesized using Tb₄O₇ and Fe (NO₃)₃·9H₂O as the main raw material by a one-step microwave process. The prepared nanoparticles were characterized by thermogravimetric and differential thermal analysis (TG-DTA), powder X-ray diffraction (XRD), scanning electron microscopy (SEM) and fourier transform infrared spectroscopy (FTIR). XRD and SEM demonstrate the successful synthesis of single phase TbFeO₃and an average grain size of 40-100 nm in diameter. The single phase structure of TbFeO₃was yet maintained after calcination at 800 °C. The photocatalytic experiment shows the high visible-light photocatalytic activity for the decomposition of methyl orange.
