| Popis: | Fe-based materials, fe2o3, fe3o4, and feooh, were synthesized by the microwave-hydrothermal process in the temperature range of 100-200 degrees 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, fe3o4 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.
