Abstract
Abstract Bi 2 O 3 /TiO 2 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 Bi 2 O 3 or TiO 2 . This was due to reduced electron‐hole recombination in the Bi 2 O 3 /TiO 2 composite, as confirmed by photoluminescence characterization. The fabrication of semiconductor composites holds great promise for enhancing the photocatalytic performance, and Bi 2 O 3 /TiO 2 is a prime example with exciting prospects for practical applications in photocatalysis.
