Abstract :
The green synthesis method utilized in this study has effectively demonstrated the environmentally friendly production of magnesium oxide (MgO) nanoparticles using red sandalwood bark extract as both a reducing and stabilizing agent. The phytochemicals present in the extract played a significant role in the formation of well-dispersed and stable nanoparticles, as confirmed by various characterization techniques. The UV-Visible absorption spectra showed a characteristic peak around 280 nm, confirming the successful formation of MgO nanoparticles. This absorption peak, coupled with the sharpness of the spectra, indicated that the nanoparticles were well-dispersed and had a narrow size distribution. The absence of significant absorption beyond 350 nm further validated the absence of larger aggregates or impurities, confirming the high quality of the synthesized nanoparticles. Characterization of the synthesized MgO nanoparticles through Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM) revealed predominantly spherical nanoparticles with a size range of 30–60 nm. The nanoparticles exhibited a minimal degree of agglomeration, which was controlled by the capping effect of the phytochemicals. The high resolution TEM images confirmed the crystalline nature of the nanoparticles through visible lattice fringes. Fourier-Transform Infrared (FTIR) spectroscopy further validated the involvement of phytochemicals in the synthesis process, with peaks indicating the presence of hydroxyl, amine, and Mg–O bonds. These findings confirmed the successful reduction of magnesium ions and stabilization of the nanoparticles by the plant extract.
