TiO₂ dopped with CuO nanocomposites are one of the most capable materials for cost-effective, reliable, and solar energy saving in addition to the development of substitute commercial in solar production and energy storage while increasing their efficiency in desired applications. This present research aims to investigate the effect of the addition on the optical and structural properties of the TiO₂ using the Sol-gel method at different (CuO) concentrations ranging between 5% and 15%. The crystal structure and optical properties of synthesized samples were examined using X-Ray Diffraction (XRD), and Ultraviolet–Visible spectroscopy (UV) respectively. All samples showed Anatase crystal structure with an observed increase in the crystal size as the CuO concertation increased from 100.9 nm to 207.3 nm. In addition, this increase in percentages has affected the optical parameters by enhancing the optical proficiency for the prepared samples with a noticed slight shift to the visible region to improve its efficiency to be used as photocatalytic and energy-saving applications in more reliable and effective methods. This study has yielded significant insights that may aid in the advancement of optoelectronic applications in industries by reducing costs. These results could be instrumental in enhancing production processes and making the use of more viable and cost-effective options for industrial operations.
