Abstract Photocatalytic degradation technology is an effective method for solving environmental pollution problems under the context of the energy crisis. The author prepared Bi2WO6 / SClCN composite photocatalysts using hydrothermal and calcination methods. The structural and morphological properties of the samples were analyzed by characterization techniques, such as X-ray diffraction and scanning electron microscopy. The photocatalytic performance was investigated using tetracycline as the target pollutant. Radical trapping experiments confirmed that h+,·O-2 , and 1O2 were the main active species during the reaction. Based on the catalysts band structure, a possible mechanism for the photocatalytic degradation reaction was proposed.
