High-purity TiO2 and CuO/TiO2 nanocomposite systems were prepared via a simple polyol solvothermal method.The synthetic precursors for nanomaterials were titanium isopropoxide (TTIP) and copper nitrate trihydrate.Several characteristic techniques, including X -ray diffraction (XRD), field-emission scanning electron microscopy (FESEM), energy-dispersive Xray spectroscopy (EDX), Fourier transform infrared (FTIR) spectroscopy, Brunauer-Emmett-Teller (BET) testing, and photoluminescence (PL) spectroscopy, were employed to investigate the as-synthesised nanomaterials.The findings showed that the undoped TiO2 and CuO/TiO2 composite samples exhibited a rice-like structure after heat treatment for 3 hours at 450 °C in an oven.The optimized MB degradation reached approximately 99.87% at 160 min, compared to bare TiO2 nanoparticles, which achieved approximately 93.81% after 180 min of UV irradiation.
