Novel detached system to MnCO3 nanowires: A self-sacrificing template for homomorphous Mn3O4 and α-Mn2O3 nanostructures

▶ A novel detached system along with solvothermal treatment was developed. ▶ Radially aggregated MnCO3 nanowires were successfully fabricated. ▶ The detached system, solvent, surfactant and reaction time were important. ▶ MnCO3 nanowires could act as the self-sacrificing template for Mn3O4 and α-Mn2O3.
