Photocatalytic coupling technologies have emerged as popular strategies to increase the treatment efficiency of dye-containing wastewater. Herein, Z-scheme Co3O4/BiOBr heterojunction (Z-CBH) was constructed and developed a photocatalytic peroxydisulfate (PDS) activator for degradation high-concentration Rhodamine B (RhB). Multiple testing techniques were employed confirm formation Z-CBHs. When 0.1 g·L–1 Z-CBH20 1.0 mmol·L–1 PDS added simultaneously under simulated sunlight irradiation, RhB could approach 91.3%. Its reaction rate constant (0.01231 min–1) much beyond sum those in Z-CBH20/light system (0.00436 PDS/light (0.0062 min–1). h+, •OH, •O2–, SO4•–, 1O2 detected dominant reactive species degradation. The potential mechanism oxidation proposed. possible intermediates determined by high-performance liquid chromatography-quadrupole time-of-flight mass spectrometry assisted with density functional theory Fukui theory. pathways put forward. toxicological properties its evaluated quantitative structure–activity relationship prediction. This work will not only provide reference developing persulfate activators but also gain an insight into toxicity intermediates.

Highly Efficient Photocatalytic Degradation of Tetracycline by Modifying UiO-66 via Different Regulation Strategies

ACS Omega, Год журнала: 2023, Номер 8(30), С. 27375 - 27385

Wastewater containing organic pollutants cause potential harm to the environment and human health. A series of zirconium-organic frameworks (UiO-66) their composites were synthesized by solvothermal methods, including band gap adjustment, heterojunction construction, metal ion doping. For model pollutant tetracycline (TC), all prepared catalysts could achieve effective degradation it. Therein, efficiency reach 95% under UV irradiation with aid catalyst, in which UiO-66-NDC was modified P–C3N4. The free radical capture experiments demonstrated that superoxide (•O2–) main oxidizing species for photodegradation tetracycline. Hence, improvement strategy catalyst would provide some enlightenment development more efficient photocatalysts dyes wastewater.
