Synthesis and characterization of γ-Fe2O3@C nanorod-carbon sphere composite and its application as microwave absorbing material

Core-shell structured γ-Fe2O3@C nanorod-carbon sphere composites have been synthesized via a facile hydrothermal method employing FeCl3·6H2O as the iron source and d-glucose as the carbon source. The core–shell structured γ-Fe2O3@C nanorods possess a uniform size with ∼500–800 nm in length, the carbon shell's thickness is ∼3–10 nm, and the γ-Fe2O3 core is homogeneously coated by amorphous carbon layer. The measured electromagnetic (EM)...
