Abstract:
In this work rod-like YMnO₃ were successfully prepared by hydrothermal method. The crystal structure and morphology of prepared samples were characterized by X-ray diffraction, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The structural information was confirmed from Raman spectrum and the functional group of the sample was studied from FTIR spectrum. X-ray photoelectron spectroscopy studies confirm the formation and oxidation states of YMnO₃. The optical properties of the prepared samples were investigated using UV-vis spectroscopy. The photocatalytic activity of YMnO₃ nanorods was evaluated by degradation of methyl orange (MO) under both ultraviolet and visible-light irradiation. The result shows that the YMnO₃ nanorods exhibit maximum photocatalytic activity in the degradation of MO.
