Microwave assisted formation of magnetic core-shell carbon nanostructure
This letter describes a facile high temperature microwave assisted process to form the magnetic core-shell carbon nanostructure from polyaniline (PANI)-magnetite (Fe3O4) nanocomposites. The amorphous combined with graphitized carbon shell is observed by the transmission electron microscopy (TEM). The crystalline metallic iron, cementite, Fe3O4 and iron oxide (Fe2O3) are observed in the magnetic core in the M̈ossbauer spectrum measurements. The increased magnetic properties are observed in the formed core-shell carbon nanostructure after microwave annealing. The formed solid carbon nanostructure can protect the material from the acid dissolution and magnetic core favors the recycling of material. © 2013 The Electrochemical Society.
