Abstract

Iron oxide (Fe₃O₄) nanoparticles with average sizes of 6 and 10 nm were synthesized by a chemical co-precipitation method from mixtures of FeCl₂·4H₂O and FeCl₃·6H₂O. They were ultrasonicated with HNO₃-oxidized MWCNTs in a solution (water/ethanol=1:1v/v) to carry out the decoration. The structure and properties of as-obtained Fe₃O₄/MWCNT composites were characterized by transmission electron microscopy, X-ray photoelectron spectroscopy, vibrating sample magnetometry, X-ray diffraction and thermal gravimetry. Results showed that the Fe₃O₄ mass fraction in the composites were 26.6 and 29.3 % for particle sizes of 6 and 10 nm, and their saturation magnetizations were 16.5 and 7.5 emu·g^-1 respectively.
