Synthesis and Characterization of ZnO and MgO Nanoparticles through Green Approach and Their Antioxidant Properties

The present work focus on the synthesis and structural characterization of ZnO and MgO Nanoparticles using geranium leaves extract as reducing agent through green approach. The prepared ZnO and MgO Nanoparticles were characterized using X-Ray Diffraction (XRD), Scanning Electron Microscopy (SEM).The elemental composition of ZnO and MgO Nanoparticles were investigated using Energy Dispersive X-ray analysis (EDAX). Based on the XRD data, the ZnO and MgO particles were measured to be 64 and 42 nanometers in size, respectively. The DPPH method was used to further test the antioxidant property of the synthesized Nanoparticles. MgO and ZnO were both found to be excellent free radical scavengers, as measured by their DPPH scavenging activities. The antioxidant property of MgO is enhanced when compared to ZnO nanoparticles.
