Enhanced Photodegradation of Tetracycline under UV‐Visible Light with a Bi₂O₃/TiO₂ Composite

Abstract

Bi2O3/TiO2 photocatalysts were successfully synthesized by the solvothermal method. Characterization using X‐ray powder diffraction, scanning electron microscopy, UV‐visible diffuse reflectance spectra, X‐ray photoelectron spectroscopy, and photoluminescence spectroscopy showed excellent photodegradation of tetracycline under UV‐visible light, compared to Bi2O3 or TiO2. This was due to reduced electron‐hole recombination in the Bi2O3/TiO2 composite, as confirmed by photoluminescence characterization. The fabrication of semiconductor composites holds great promise for enhancing the photocatalytic performance, and Bi2O3/TiO2 is a prime example with exciting prospects for practical applications in photocatalysis.
