Hydrothermal Synthesis and Characterisation of Mn₂O₃ Nanowires

Abstract:

In this Letter, we reported the facile synthesis of manganese (III) oxide (Mn₂O₃) nanowires via the facile hydrothermal treatment in the presence of ammonia, which were prepared simply by hydrothermal treatment of commercial bulky Mn₂O₃ crystals at 160 ^oC for 24 h. The obtained Mn₂O₃ products consist a large quantity of nanwires with the diameters of 30-90 nm, and lengths ranging from 1 to 10 μm. Such high quality nanowires with high aspect ratio have a variety of promising applications. The simplicity of hydrothermal process, cheapness, and availability of raw materials, without the need of catalyst or template, are advantages favoring industrial manufacturing in scaled-up process by the novel method. X-ray and transmission electron microscopy, electron diffraction, and scanning electron microscopy have been employed to characterize these materials. In addition, the possible growth mechanism of the Mn₂O₃ nanowires was also proposed. The growth of Mn₂O₃ nanowires occurred via a dissolution-recrystallization process.
