چکیده مقاله

Abstract Present report focuses on the preparation and characterization of Mn2O3 nanostructures. First, two different manganese precursors were prepared by reaction between manganese acetate tetrahydrate and phthalic acid with molar ratios of 1:1 and 1:2 in solid phase. In the second step, Mn2O3 nanostructures were obtained via a simple solid-state thermal decomposition route. Furthermore, the effect of calcination temperature and metal-toligand ratio on the morphology and particle size of Mn2O3 was investigated. The crystalline structure and morphology of the final products were studied by X-ray powder diffraction, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Based on the SEM and TEM images, it was found that by increasing the metal to capping agent ration, particle sizes of the products were decreased.
