Abstract The Cl‐doped BiOBr photocatalysts were used to degrade tetracyclin, which was usually difficult in wastewater, reduce secondary pollution the environment. In this paper, composites prepared by a hydrothermal method using bismuth nitrate as source, potassium bromide bromine chloride chlorine and deionized water solvent. physical structure, chemical composition, surface morphology, optical properties, charge transport of characterized analyzed XRD, XPS, TEM, UV–vis DRS, photoluminescence (PL), electrochemical impedance spectroscopy (EIS), Brunauer–Emmett–Teller (BET). successful preparation with tetragonal crystal system confirmed XRD characterization. SEM TEM images that samples have lamellar stacking structure. PL, photocurrent, EIS studies on showed had good separation efficiency. catalytic performance investigated tetracyclin (TC) target contaminant, results C 2 ─BiOBr exhibited strong photodegradation TC, degradation efficiency 76.2%. excellent attributed formation doped energy levels improved visible light absorption efficient transfer/separation. Free radical scavenger ∙OH h + generated photocatalyst responsible for TC. Two possible pathways TC proposed based HPLC‐MS/MS detection their intermediate products tended be less toxic. Finally, stability reproducibility catalyst cycling experiments. This study provides reference practical applications.
