Hybrid nanostructured materials currently offer a potential approach for variety of applications due to improvements in their physio-chemical characteristics. Techniques XRD, TEM-HRTEM, SAED, and UV-DRS were used characterize the Cu2ZnAl2O4 (CZA) material. Without any secondary phases with an average crystallite size 40 ​nm, X-ray diffraction pattern examination demonstrates increased crystalline structure. A highly crystalline, polydisperse CZA nanostructure was visible using TEM-HRTEM SAED. The nanostructure's light-absorbing behavior is presented by analysis, which found that predicted bandgap energy 5.0 ​eV. In this article, we describe easy chemical synthesis hybrid works well as catalyst break down acid red 88 (AR-88) dye under UV, sunlight, low light conditions. Additionally, it studied determine how modify working electrode's surface enable detection lead tin metal ions. With 93.1% degradation comparison work on decolorizing AR-88 presence both sunlight darkness, looked at decolorization dye. By graphite electrode paste cyclic voltammetry analyze synthesized sample 1 ​N KCl, discovered had outstanding redox reaction capabilities.
