Synthesis of zinc oxide nanoparticles with banana peel extract from musa acuminata plaintain (pisang tanduk): effect on pH value and reaction time

The zinc oxide nanoparticles (ZnO NPs) is synthesized using Musa Acuminata Plaintain banana peels extract (BPE). This synthesis is considered an ideal method for synthesis as it is using biodegradable material which are cost-effective and easily to access. Effect of the pH value and reaction time on the morphology of the ZNP were studied. The characterization of the synthesized ZNP is analyzed using Fourier Transform Infrared Spectroscopy (FTIR), X-Ray Diffractometer (XRD), Ultraviolet Visible (UV-Vis), Brunauer-Emmett-Teller (BET), Zeta Potential and High Performance Liquid Chromatography (HPLC). The XRD pattern shows that the ZnO NPs have a crystalline hexagonal wurtzite structure. The band gap energy is found in the range of 3.28-3.41 eV. The optimum condition for the synthesis of the nanoparticles are found at pH 12 and reaction time of 60 minutes.
