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.

In this research, a novel spinel architecture of pure CdAl2O4 and Zn (0.025–0.075 M) doped nanoparticles were synthesized. The PL ESR outcomes shows that the doping played an effective role to prevent e−-h+ pairs recombination in during photocatalysis. (0.075 M)-CdAl2O4 provided maximum photodegradation efficiencies for BB BG with removal efficiency 91 96% just 90 min as compared other samples remain stable after fifth cycle. Such pave approach sustainable photocatalytic technologies diminish global influence organic inorganic dyes.

Increasing tetracycline and ciprofloxacin pollution seriously threatens the ecological environment human health, it is important to remove antibiotic contaminants from water environment. Herein, NiO/Fe2O3/C nanocomposites were synthesized by hydrothermal method, catalysts characterized different analytical techniques explore their physical chemical properties about removing antibiotics. Through SEM, TEM, XRD, XPS, UV-Vis-DRS obtain photocatalysts microstructure, crystalline phase structure, atomic states optical absorption properties. The photocurrent response electrochemical impedance testing found that addition of carbon materials effectively improves electron migration transport efficiency between NiO Fe2O3, reduces recombination photogenerated electron-hole pairs, photocatalytic performance catalyst. Antibiotics with used as standard for under visible light irradiation. removal rate (TC, 40 mg/L) was 94% 80 min 96% (CIP, 20 after 30 light. degradation kinetic computed K value 0.2CFNO 0.0371 min−1 TC; which almost 9.2 times higher than FZO (0.004 min−1), 0.087 CIP, 79 those observed (0.0011 min−1).
