Method for MN₃O₄nanoparticles by solid-state decomposition of exfoliated MNO₂nanosheet

摘要

A method of preparing one-dimensional trimanganese tetroxide (Mn3O4) nanoparticles from an exfoliated two-dimensional manganese dioxide (MnO2) nanosheet using a solid-state decomposition method, and Mn3O4 nanoparticles prepared according to the method are provided. The Mn3O4 nanoparticles can be prepared at a very low temperature without using an organic solvent or a chemical additive, compared to conventional synthesis methods.
