In this study, magnetite nanoparticles (Fe3O4 NPs) were successfully synthesized using Baccaurea ramiflora leaf extracts and characterized. The results showed that the Fe3O4 NPs had a good crystalline structure and catalytic activity, making them suitable for wastewater treatment.
In this study, magnetite nanoparticles (Fe3O4 NPs) were synthesized using Baccaurea ramiflora leaf extracts and characterized by visual observation, UV-Vis, FTIR, XRD, FESEM, and EDS. The UV-Vis spectrum showed continuous absorption at 300-500 nm, confirming the formation of Fe3O4 NPs. FTIR revealed that compounds containing the O-H group act as reducing agents during Fe3O4 NPs formation. Agglomerated spherical NPs were observed in the FESEM image. The prominent peak at similar to 6.4 keV in the EDS spectrum ascertained the existence of Fe, while the sharp peak at similar to 0.53 keV confirmed the presence of elemental oxygen. XRD patterns affirmed the crystalline nature. The size of as-synthesized NPs was observed to be 8.83 nm. The catalytic activity of Fe3O4 NPs for the reduction of methylene blue (MB) dye was monitored by UV-Vis. The maximum absorption peak of MB dye at 664 nm was almost diminished within 20 min, which revealed Fe3O4 NPs could be an excellent catalyst for wastewater treatment.
