摘要/Abstract

Abstract:

Novel three-dimensional (3D) cage-like α-Fe₂O₃ nanostructures were successfully prepared by a template-free hydrothermal synthetic route. The characterization results indicated that the nanostructures were assembled by α-Fe₂O₃ nanoparticles. The assembled cage-like α-Fe₂O₃ nanostructures show weak ferromagnetic behavior at room temperature, and the corresponding values were higher than those of α-Fe₂O₃ nanoparticles reported in the literature.

Key words: Template-free; α-Fe2O3; Nanostructure
