Abstract

A hierarchical sea-urchin-like SnO₂@Fe₃O₄ nanostructure was synthesized via a simple two-step liquid-phase method. The SnO₂ nanorod epitaxially grew in the radial direction on the surfaces of Fe₃O₄ microspheres. The microwave absorbing properties of the hierarchical SnO₂@Fe₃O₄ nanostructure were studied. The hierarchical SnO₂@Fe₃O₄ nanostructure showed enhanced microwave absorbing properties compared to those of the primary Fe₃O₄ microspheres. The maximal refection loss (RL) of the hierarchical SnO₂@Fe₃O₄ nanostructures was −20.0 dB at 14.5 GHz with an absorber thickness of 8 mm. These results demonstrate an efficient method for designing new types of microwave-absorbing materials with high performances.
