Abstract  

To utilize visible light more efficiently in photocatalytic reactions, Bi2O3/CaO photocatalysts were prepared by a mechanical mixing method and characterized by X-ray diffraction (XRD) and UV–vis spectroscopy. UV–vis spectroscopy results showed that the photocatalysts have a wide absorption band in the range of visible light. The photocatalytic activities of obtained Bi2O3, CaO, and Bi2O3/CaO samples were evaluated by methylene blue degradation under visible light irradiation. It was found that the Bi2O3/CaO sample exhibited the highest photocatalytic activity.
