Nano-sized Mn3O4 and β-MnOOH from the decomposition of β-cyclodextrin–Mn: 1. Synthesis and characterization

• The decomposition of metal oxides is a promising method to synthesize metal oxides.
• Nano-sized Mn oxides contain Mn3O4 and β-MnOOH have been prepared.
• The decomposition of β-cyclodextrin–Mn complex in different temperature forms Mn oxides.
• A simple and high-yield method to synthesize Mn oxides was reported.

Nano-sized Mn oxides contain Mn3O4 and β-MnOOH have been prepared by a simple and high-yield method using β-cyclodextrin as a ligand for Mn ions, and decomposition of this Mn complex. Scanning electron microscopy, transmission electron microscopy, thermogravimetric analysis, Fourier transform infrared spectroscopy and X-ray diffraction spectroscopy have been used to characterize morphologies and the phases of these prepared nano-sized Mn oxides.
