Solvothermal synthesis and characterization of α-Fe2O3 nanodiscs and Mn3O4 nanoparticles with 1,10-phenanthroline

► Preparation of α-Fe2O3 nanodiscs and Mn3O4 nanoparticles was present. ► Simple solvothermal route was used for fabricating Fe2O3 and Mn3O4 nanostructures. ► Nanostructures were prepared with using of 1,10-phenanthroline as complexing agent. ► This method is suitable for scale-up production of nanostructures.
