“…Though diminishes significantly, weak absorption from these bands remain present after the heat treatment even at 800 C. The appearance, thermal stability and temperature dependence of these absorption bands in IR spectra of LaFeO 3 synthesized by other methods involving organic species is common. Examples include the LaFeO 3 synthesized by gel combustion [32,45,46], microwave assisted combustion [31], solid state reactions [47], solegel [20] and hot soap [26] methods.…”

“…It was found that the structures and properties of the materials were highly dependent on synthesis process of its precursor powders, so the improvement of preparation method of these powders is paid much attention by researchers [19]. The preparation of LaFeO 3 have been achieved by many methods, including solid-state reaction [19], sol-gel [3,8,20], hydrothermal [18], microwave assisted [2] and polymerizable complex method [21,22] etc. Generally solidstate reaction method required high temperature ([900°C) for long duration which results in poor homogeneity and high porosity with micrometer particles.…”

LaFeO 3 nanospheres were synthesized by hydrothermal method followed by calcination. Citric acid was found to be key factor to the purity and the surface morphology of the LaFeO 3 nanospheres. The obtained nanospheres have been structurally characterized by XRD which confirms the single crystalline orthorhombic structure. The structural information of the nanosphere was also confirmed from the Raman spectrum. HRSEM and AFM revealed that the prepared sample has been composed of spherical like morphology with an average size of about 45 nm. From XPS analysis, the chemical state of the LaFeO 3 nanospheres was confirmed. Magnetic measurement indicates the products shows weak magnetic behaviour. The UV-Vis spectroscopy analysis shows strong absorption at 466 nm which confirms that the obtained material has excellent visible light absorption ability. Furthermore, the photocatalytic experiment demonstrates that the prepared LaFeO 3 nanospheres exhibit well and stable photocatalytic activity for decomposition of methyl orange under visible-light irradiation.
