Abstract

This research aims to know the relationship between the amount of FeClx added in the reaction and the morphology of Fe3O4/CNT nanocomposite which is the synthesis result using sonochemical method. The Fe3O4/CNT nanocomposite is synthesized from iron sand and functinalized CNT using sonochemical method with the variations of FeClx volume parameters are 10, 20, and 30 mL. The Fe3O4/CNT nanocomposite is then characterized using XRD, TEM, and VSM. The characterizing results using XRD for every variation of FeClx volume show that the diffraction peak appearing in the results are the characteristic of CNT and Fe3O4 with a little of α-Fe2O3. The characterizing results using TEM show that there are agglomerations in the Fe3O4/CNT nanocomposite at every variation of FeClx volume which the diameters of CNT are respectively 33.08, 27.02, and 27.64 nm. The diameters of Fe3O4 are respectively 20.18, 15.44, and 18.37 nm. The characterizing results using VSM for every variation of FeClx volume show large saturation magnetization values respectively 11.33, 21.14, and 24.72 (emu/g), with small coercivity values respectively 7.69, 7.21, and 6.94 (x10-3 T). It is indicated that the Fe3O4/CNT nanocomposite has a super-paramagnetic property.
