<p>In the present era, nanomaterials have many uses due to their superior chemical and physical characteristics. The electrochemical deposition approach, which is quick, simple, and affordable, is one of the key techniques for creating nanocomposites (Al₂O₃/ZnO). Advanced methods like X-ray diffraction (XRD), field-emitted scanning electron microscopy (FESEM), microscopy using transmission electrons (TEM), ultraviolet-visible (UV-Vis), energetic dispersive x-ray (EDX), and atomic force microscopy, also called AFM, are used to analyse the nanocomposite. According to the investigation, the nanocomposite had an average crystal size of 8.4 nm, a band gap value of 3.23 eV, and a nanorod form.</p>
