Summary: | [Display omitted]
•Nanostructure of MgO were synthesized by a simple method, using new templates.•Different templates affect on the size and species of particles.•MgO nanostructuere were utilized for decolorization of Indigo carmine.
Magnesium oxide powders have been prepared by simple method using different templates as Hexamine (T1), alkylate-hexamine salt (T2) and alkylate–dihexamine salt (T3). The annealed products were systematically investigated by using X-ray diffraction (XRD), energy dispersive X-ray spectroscopy (EDX), scanning electron microscopy (SEM) and UV–Visible absorption. It was found that the formation of nanoparticle could involved the role of performed “nucleus” and used template to control the growth rate of nucleuses. The results were shown that different templates affect on the size and species of particles. In this study, the crystallite size of the MgO products were in a range from 4 to 7nm. The optical band gap of MgO nanoparticles was in the range 4.27–4.77eV. The morphology of MgO was nanospheres or nanokongelemere-like. In this investigation photocatalytic degradation of Indigo carmine (IC) in water was studied. The effects of some parameters such as pH, amount of catalyst, initial concentration of dye were examined. |
