Controlled synthesis of bismuth oxide microtetrahedrons and cubes by precipitation in alcohol-Water systems PROJECT TITLE :Controlled synthesis of bismuth oxide microtetrahedrons and cubes by precipitation in alcohol-Water systemsABSTRACT:Bismuth oxide (Bi2O3) microtetrahedrons and cubes were synthesised in large quantities by a chemical precipitation and refluxing method with BiCl3 and NaOH as reactants in alcohol-water systems. The products were characterised by X-ray powder diffraction (XRD), field emission-scanning electron microscope (FESEM), energy-dispersive X-ray spectroscope (EDS) and SEM. XRD analyses showed that the as-prepared Bi2O3 was body-centred cubic (bcc) (γ) phase and had a high degree of crystallinity. FESEM and SEM micrographs indicated that tetrahedral Bi2O3 with the edge length of 1-5 μm was formed. The morphology of the final products changed into microcubes by increasing the amount of dispersant. The result of the influence of reaction temperature on products revealed that the pure-phase γ-Bi2O3, as well as well-defined tetrahedron, was obtained at the temperature ≥75°C.
