The present investigation reports, the synthesis of manganese oxide (a-Mn2O3) nanobundles using thermal
decomposition and its physicochemical characterization. The a-Mn2O3 nanobundles have been prepared
using manganese oxalate dihydrate powders as precursor in the presence of oleylamine and
triphenylphosphine as solvent and capping agent. Transmission electron microscopy (TEM) analysis
demonstrated Mn2O3 nanobundles compose of nanospheres with diameter 30 nm. The products were
characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray
(EDX), X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FT-IR) spectroscopy.
Manganese oxide nanocrystals have been prepared under different condition. The controlled experimental
results showed that the use of oleylamine and triphenylphosphine as the solvent and capping agent in
the chemical process played important role in the formation of the final products.
