In this study, nanocomposites of monoferrite-activated carbon (Ferrite-AC) have been prepared by mechanosynthesis technique. Nanocomposites can be utilized as adsorbent for desulfurization of hydrocarbon liquid fuels. Nanocomposites were characterized by scanning electron microscopy (SEM), energy dispersive X-ray (EDS) analysis, Fourier transform infrared (FTIR), X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Brunauer-Emmet-Teller (BET) and vibration sample magnetometer (VSM). Results showed that NiFe2O4-AC had better performance between other adsorbents. Adsorption rate of dodecanethiol was improved by increasing NiFe2O4-AC concentration. XPS results showed that the dodecanethiol was oxidized by the catalyst surface. BET surface erea of NiFe2O4-AC nanocomposite was 626 m2/g with porous structure.
