TLDR
In this paper, single-crystal tetragonal α-MnO2 nanotubes have been successfully synthesized by a facile hydrothermal treatment of KMnO4 in the hydrochloric acid solution.Abstract:
Single-crystal tetragonal α-MnO2 nanotubes have been successfully synthesized by a facile hydrothermal treatment of KMnO4 in the hydrochloric acid solution. The sample has been characterized by X-ray powder diffraction, field emission scanning electron microscopy, transmission electron microscopy, and orientation dependent Raman spectroscopy, which indicates the nanotubes have high-quality crystalline and shape-dependent optical properties. The morphology evolution of the sample reveals that the nanotubes are formed via the solid nanorod by a chemical etching process.read more

Synthesis and formation mechanism of manganese dioxide nanowires/nanorods.
TL;DR: It is interesting to find that all the MnO( 2) one-dimensional nanostructures have a similar formation process: delta-MnO(2), which has a layer structure, serves as an important intermediate to other forms of MnO (2), and is believed to be responsible for the initial formation of Mn olympic nanostructure.
