Iron oxide nanomaterials have gained scientific focus for environmental remediation. This study aimed to compare the structural properties of magnetite using chemical and green synthesis methods, applying XRD, FT-IR, SEM, EDS, TGA, DLS, and zeta potential characterization techniques. The XRD analysis showed that the average particle size of chemical and green-synthesized magnetite was 11nm and 8.4nm, respectively. FT-IR analysis of green-synthesized magnetite showed the shifting of stretching vibration of C=O and C-O in green-synthesized magnetite from 1646 cm-¹ to 1644 cm-1 and 1052 cm-1 to 1065 cm-1 after capping with leaf extract SEM images of green-synthesized magnetite was found to have some extent of aggregation due to the capping and stabilizing action of (e.g., polyphenols, flavonoids), present in leaf extract influence the nucleation and growth process during synthesis. The bio-organic matrix likely leads to steric hindrance and variation in crystal growth, resulting in less-defined shapes and reduced aggregation compactness. The EDS spectrum of green synthesized confirmed the existence of biomolecules (C). The hydrodynamic diameters were 150nm for green-synthesized and 158nm for chemically synthesized magnetite, while zeta potential was found to be -50 mV and -47 mV, respectively. This study demonstrated improved crystallinity and enhanced stability of green-synthesized magnetite compared to chemically synthesized magnetite. Therefore, the environmentally sustainable green synthesis method offers a promising alternative to the synthesis of magnetite for environmental applications.
