The rational design of BiOBr photocatalysts with optimized surface properties and enhanced photooxidative capacities is crucial. This study proposes a synergistic strategy combining hydroxyl-rich solvents polyvinylpyrrolidone (PVP) surfactants to modulate the structural electronic through solvothermal approach. resulting self-assembled microspheres demonstrated exceptional efficiency in degrading ciprofloxacin (CIP), methyl orange (MO), rhodamine B (RhB). Among synthesized variants, BiOBr-EG-PVP (fabricated ethylene glycol PVP) exhibited highest photocatalytic activity, achieving near-complete removal 20 mg/L CIP RhB within 10 min under visible light irradiation, degradation rates 60.12–101.73 times higher than pristine BiOBr. characterization revealed that (EG) not only induced formation but also introduced abundant hydroxyl groups, which simultaneously hole-mediated oxidation capabilities. incorporation PVP further promoted development hierarchical honeycomb-like synergistically both group density potential interfacial engineering. Density functional theory (DFT) calculations confirmed performance originated from an increased oxygen content. work elucidates effects surfactant modification fabrication advanced BiOBr-based photocatalysts, providing new insights for high-performance photocatalysis environmental remediation.
