Fe-based materials, Fe2O3, Fe3O 4, and FeOOH, were synthesized by the microwave-hydrothermal process in the temperature range of 100-200 C and under very short reaction times of 15 min to 2 h. Under microwave-controlled hydrolysis and redox reactions, cube-like Fe2O3 was crystallized using FeCl3, Fe 3O4 particles were crystallized from FeCl2 and FeOOH nanorods were crystallized using FeCl3. The Fe-based materials were fabricated to make anodes and cathodes of lithium-ion battery and supercapacitor electrode materials to study their potential electrochemical applications. The electrochemical results showed that FeOOH had better anode capacity as lithium-ion batteries than those of Fe2O3 and Fe3O4. The present results suggest that the microwave-hydrothermally synthesized Fe-based materials are promising lithium-ion battery anode materials.
