A facile low-temperature route for preparing monodisperse Mn3O4 nanopolyhedrons from amorphous MnO2 nanoparticles
In the paper, we firstly show a facile hydrothermal route for synthesizing monodisperse Mn3O4 nanopolyhedrons directly used new-made amorphous MnO2 nanoparticle with its mother solution as precursors. The hydrothermal process was performed at 160 ºC [...]
