Green synthesis and characterization of zinc oxide nanoparticles using aqueous bark extract of Malayan cherry (Muntingia calabura)
Zinc oxide nanoparticles (ZnO NPs) were synthesized and characterized through the green synthesis pathway using the bark extract of Muntingia calabura with zinc nitrate hexahydrate as the salt precursor and deionized water as the green solvent. The phytochemicals found in the bark extract served as...

| description | Zinc oxide nanoparticles (ZnO NPs) were synthesized and characterized through the green synthesis pathway using the bark extract of Muntingia calabura with zinc nitrate hexahydrate as the salt precursor and deionized water as the green solvent. The phytochemicals found in the bark extract served as the stabilizing and reducing agent in the synthesis of ZnO NPs. The synthesized ZnO NPs were characterized using Fourier Transform Infrared Spectroscopy (FTIR), UV-Visible Spectroscopy (UV-Vis), X-ray Diffraction (XRD), Field Emission Scanning Electron Microscopy (FESEM) and Energy Dispersive X-ray Spectroscopy (EDX). Based on the results of this study, the phytochemicals in the bark extract that involved in the reaction could be observed in the FTIR spectrum. The formation of ZnO NPs could be proved by the presence of Zn-O stretching at the peak 459 cm-1 in the spectrum. The UV-Vis spectrum showed that the maximum absorption wavelength of ZnO NPs was 373 nm with a band gap energy of 3.32 eV. XRD revealed that the structural identity of ZnO NPs to be hexagonal wurtzite structure with a crystallite size of 48.90 nm. Based on FESEM results, the morphology of ZnO NPs was found to be spherical shape with a particle size ranging from 38.0 nm – 71.4 nm. The elemental composition of ZnO NPs was characterized by EDX which proved the presence of zinc and oxygen. |
