One-step pyrolysis route to C/Fe_3O_4 hybrids from EDTA ferric sodium salt

摘要

C/Fe_3O_4 hybrid materials have potential applications in sensors and anode materials for lithium-ion batteries. In this text, a one-step pyrolysis method was used to prepare C/Fe_3O_4 hybrid materials from EDTA ferric sodium salt. The magnetic Fe_3O_4 nanoparticles can be homogeneously incorporated into carbon materials to form C/Fe_3O_4 hybrids during the reaction. The morphology and magnetism of the C/Fe_3O_4 hybrids are strongly affected by pyrolysis temperature. This method supplies an ideal template to facilely synthesize C/metal-oxide hybrid materials from EDTA metallic salts.
