In this study, the nanocomposite of eggshell membrane is synthesized with ZnO by the chemical bath deposition (CBD) method, and eggshell membrane, which is used as a template, and decomposed. The end product obtained is nanoflowers of zinc oxide (ZnFs). The petals of nanoflowers obtained are of hexagonal cross-section similar to the unit cell structure of zinc oxide. The CBD parameters of temperature, reaction time, and solution pH were varied extensively during this study to obtain optimized parameters for the growth of ZnFs. The obtained nanoflower structure was analyzed using various characterization techniques of Scanning Electron Microscopy (SEM), Energy Dispersive X-Ray Spectroscopy (EDX), X-Ray Diffraction (XRD), and Fourier Transform Infrared Spectroscopy (FTIR).
