In the present study, we report the synthesis of TiFe2O4/Activated Carbon (AC) nanocomposite and its application for heavy metal (Cd) adsorption. The characterizations were conducted by means of XRD, SEM, FTIR, UV–Vis, and AAS to investigate structure, morphology, functional groups, and Cd adsorption characteristics of the prepared nanocomposite, respectively. The formation of TiFe2O4 with a cubic spinel structure and a crystallite size of 9.6 nm was evaluated from the XRD data analysis. However, due to low composition of AC in the nanocomposite, the diffraction peaks of AC were not detected. The SEM data analysis showed the agglomeration of the nanocomposite in nanometric size with irregular shape. FTIR data analysis revealed the presence of AC containing oxygen functional groups such as C-O and C=O. Furthermore, Fe–O bonds were also detected at a wavenumber of 528 cm-1. The UV–Vis data analysis showed the bandgap of the TiFe2O4/AC nanocomposite of 2.82 eV. Moreover, the results of AAS characterization showed the adsorption capacity increased as the contact time increased. Interestingly, the percentage of Cd absorption of TiFe2O4/AC nanocomposite was quite high, reaching 93.36%. © 2025 American Institute of Physics Inc.. All rights reserved.
