Photocatalytic applications of A5-mPmH-Zr/CuTiO₃ nanocomposite synthesized by simple hydrothermal method

The current investigation presents findings on the synthesis of nanocomposites consisting of CuTiO₃ and Zr/CuTiO₃. These materials were prepared using the hydrothermal technique, with zirconium metal being incorporated onto the CuTiO₃ matrix. A comprehensive investigation of the band gap was conducted. The observed band gaps for Zr/CuTiO₃ and CuTiO₃ was determined to be 2.7 eV and 3.3 eV respectively. This finding implies that Zr/CuTiO₃ exhibits enhanced electron mobility capabilities. The experiment involved subjecting the synthesized nanocomposite to a degradation analysis of Alizarin dye. Remarkably, the nanocomposite exhibited impressive degradation efficiency, with nearly 99 % of the dye being decomposed under the influence of light. The Zr/CuTiO₃ nanostructure exhibited remarkable antibacterial efficacy, as evidenced by its ability to inhibit the growth of B. subtilis and E. coli with a diameter of 19±0.4 mm and 16±0.3 mm respectively under light conditions and 14±0.2 mm and 10±0.4 mm under dark conditions respectively.
