Investigation of Metal Oxide Nanoparticles by Using Punica granatum Extract

Zinc oxide has significant importance as it has various applications in many industries due to its versatile properties which can be enhanced by production at the Nanoscale. Major applications of ZnO in material science are due to its greater refractive index value, considerable thermal conductivity, binding, biocompatibility, and anti-bacterial characteristics. Many physical and chemical Synthesis techniques are adopted but along with synthesis, these methods carry impurities that lead to a reduction of yield of pure Nanoparticles. Adoption of a sustainable route i.e. Green route for the synthesis of Nanoparticles considerably enhances the properties and effectiveness of NP’s, as it is a less hazardous method than other chemical and physical methods. Zinc oxide NPs have been successfully prepared by green synthesis using biological substrate (Fresh Punica granatum seed). Characterization techniques i.e. XRD, DRS, FTIR, UV reveals crystalline structure, Band Gap, Transmission, and absorption spectra of the sample. Miller indices values from the XRD plot are (100) (002) (101). The average grain size obtained from XRD analysis is 17nm and crystal geometry is hexagonal. Grain size ranges from 15nm to 40nm can have the best effect for antibacterial and antifungal applications. Bandgap energy shows the semiconductor range of ZnO Nanoparticles.
