STRUCTURAL AND MORPHOLOGICAL INVESTIGATION OF MGONPS SYNTHESIZED FROM RUBBER SEED HUSK VIA SEM, XRD, AND FTIR
Abstract
This study investigates the green synthesis of magnesium oxide nanoparticles (MgONPs) using rubber seed husk extract as a natural reducing agent, presenting an eco-friendly alternative for nanoparticle production. A shift in the colloidal solution's color initially indicated the formation of MgONPs. Fourier Transform Infrared Spectroscopy (FTIR) confirmed the presence of key functional groups, with a strong O—H stretching peak at 3700 cm⁻¹ (indicative of phenol) and absorption bands at 1012 cm⁻¹ and 1634 cm⁻¹, corresponding to amine and alkane bending vibrations. X-ray Diffraction (XRD) analysis revealed high crystallinity, with distinct peaks associated with various crystallographic planes. Scanning Electron Microscopy (SEM) images exhibited irregularly shaped nanoparticles with noticeable agglomeration, likely influenced by the phytochemical composition of the extract. These results highlight the potential of rubber seed husk for sustainable MgONP synthesis, emphasizing its applications in biomedicine and environmentally conscious nanotechnology.
