Abstract

A unique approach for customizing nanowire zinc oxide thin films on nanoporous anodic Al2O3 (nPAA) was developed in this study, which included the use of an electrochemical procedure to manufacture nanowire zinc oxide thin films on nanoporous anodic Al2O3 (nPAA). With a single step of anodization at 25 oC and low voltage, we were able to produce a conventional nPAA template. The embedding of ZnO arrays in nPAA pores was a subsequent step in the process of creating the device. During the electrodeposition process, the techniques of cyclic voltammetry, linear sweep voltammetry, and chronoamperometry were used to determine whether zinc oxide was being electrode deposited on the nPAA. The results of these measurements were compared to the results of the other measurements. For the investigation of ZnO/nPAA assemblies, field emission scanning electron microscopy (FE-SEM) and dispersive X-ray spectroscopy (DXS) was used to determine the morphological structures and chemical compositions of the assemblies, as well as to determine their mechanical and electrical properties (EDX). Several developing sectors have the potential to profit from the materials that have been discovered so far, including electronics, energy, and photocatalysis.
