The Bi2O3-TiO2 nanocomposite material were prepared by the precipitation method and sonication technique, and used Rhodamine 6G (Rh 6G) under UV-Light on 365 nm in the elevated photocatalytic activity of Bi₂O₃-TiO₂that TiO₂. The nanocomposite material was characterized by high-resolution scanning electron microscopy with elementary dispersive X-ray, high-resolution transmission electron microscopy, X-ray diffraction method, photoluminescence spectroscopy, and diffuse reflectance spectra. This nanocomposite material was used for photodegradation of Rh 6G dye at various parameters. The mineralization of dyes is confirmed by chemical oxygen demand measurements. An achievable mechanism is proposed for higher activity of Bi₂O₃-TiO₂ than that of TiO2 nanocomposite material. This nanocomposite material was found to be stable and reusable. This Bi₂O₃-TiO₂ nanocomposite material had higher photocatalytic, antibacterial, and electrochemical activities than that of TiO₂
