In this paper,hierarchically porous Fe2O3 /CuO composite monoliths were first successfully synthesized by a mild method using silica monoliths as templates.The structure of composite monoliths was characterized by X-ray diffraction,scanning electron microscopy,nitrogen adsorption-desorption.The results indicated that the molar ratio of Fe to Cu had a great influence on the crystal phase of Fe2O3,pore size and the structure of the macroporous wall.The Fe2O3 /CuO composite monoliths consist of hierarchically macroporous and mesoporous structure,while the sample with the Fe/Cu molar ratio of 2:1 possesses tighter wall structure than other samples.It is expected that asprepared Fe2O3/CuO composite monoliths have potential applications in several fields as catalysts,catalyst supports,chemical sensors and high-performance liquid chromatography (HPLC).
