The accumulation of potential antibiotics in water is potentially harmful to human beings and the environment. In this paper, a novel composite catalyst, Bi4O5I2/glucose-modified Bi2O2CO3 (BGBCO) with high ciprofloxacin (CIP) removal rate, was rapidly synthesized by low-temperature hydrothermal method. BGBCO demonstrated best photocatalytic activity after 100 min irradiation 65 W energy-saving lamp. apparent kinetic constants are 7.20, 2.28, 1.41 times Bi2O2CO3, Bi4O5I2, glucose-modified respectively. Experimental results characterization show that significant improvement performance can be attributed more active sites, wider visible light absorption range, improved photogenerated carrier separation rate. Free radical capture experiments confirmed •O2- h+ primary species responsible for degradation CIP. toxicity prediction showed CIP products decreased significantly. Based on various results, possible mechanism pathway were proposed. This study provides valuable insights modification Bi2O2CO3-based heterojunction materials their application purification water.

Photocatalytic aerobic oxidation desulfurization (PAODS) has emerged as a sustainable means for the of fuels, which is, however, limited by low efficiency electron–hole separation in currently available catalytic systems. In this study, we report design and synthesis ZnIn2S4 quantum dot (QD)/Mo-doped WO2.72 nanowire 0D/1D Z-scheme heterojunction photocatalyst PAODS thiophenic sulfides. We elucidate that incorporated Mo sites facilitate localized surface plasmon resonance (LSPR) effect generation hot electrons also act high-activity sulfide oxidation. The integration QDs improves adsorption visible light facilitates pairs. demonstrates outstanding activity with mass specific 3.91 mmol g–1 h–1. particular, it successfully achieves deep real diesel, effectively reducing sulfur content to 9.4 ppm, suggests its appealing practical potential. These findings offer valuable insights, both from scientific perspective, develop high-performance photocatalysts processes.
