A Room Temperature Synthetic Route to Mn3O4 Nanoplates
Abstract:Nanoplates of Mn3O4 were prepared by redox reactions of Mn(CH3COO)2·4H2O taking place in short chain n-alkylamine aqueous solutions such as n-butylamine, n-propylamine and n-hexylamine at room temperature. Phase purity was confirmed by powder X-ray diffraction. The high resolution transmission electron microscopy revealed the rectangle shape of Mn3O4 nanoplates with the average edge length of 22 nm and width of 19 nm. The prepared Mn3O4 nanoplates exhibited a coercive field of 5034 Oe at 10 K. The possible formation mechanism was also discussed.
