Study on the effect of annealing temperature and photocatalytic properties of TbMnO3 nanoparticles
چکیده انگلیسی
In the present study, TbMnO3 nanoparticles were prepared by hydrothermal method and annealed at different temperatures. The prepared samples were characterized by means of X-ray diffraction (XRD), Raman analysis, Atomic force microscopy (AFM), Magnetic force microscopy (MFM) and UV-vis absorption spectroscopy (UV-vis). The average particle size of TbMnO3 nanoparticles annealed at 800 and 900 °C was found to be 45 and 60 nm. Optical energy bandgap of the samples were carried out using UV-vis absorption spectroscopy. Finally the effect of different sized TbMnO3 nanoparticles as a catalyst for methyl orange (MO) dye degradation under UV light irradiation was analysed.
