The oxygen-vacancy (OV)-rich BiOBr exhibits higher photocatalytic activity than that of the OV-deficient one. interaction target substrate with surface OV sites should be essential for high activity, but it is not well understood so far. Here, we used a cyanotoxin cylindrospermopsin (CYN) as model to investigate specific adsorption pollutants highly hydrophilic groups on BiOBr. We found CYN rich OVs much stronger poor OVs, and also degradation rate CYN. Various experiments indicated strong OV-rich originates from between sulfate group sites. Density functional theory calculations suggest that, sites, Brönsted acid (OHB) are formed through dissociative water molecules. combining effect hydrogen bonding these OHB coordination Lewis Bi make quite strong. Such can explain rapid CYN, which proceeds direct oxidation by h+ or OHB-derived •OH. Based ultra-performance liquid chromatography–tandem mass spectrometry analysis, begins via hydroxylation at C5–C6 double bond in uracil ring •OH, further degraded two pathways. This work provides deeper understanding critical roles processes photocatalysis organic pollutant removal.

In our current research, an intriguing magnetic nano sorbent Fe3O4@Zr-MOF was synthesized in the lab. We used this adsorbent for successfully removing tetracycline (TC) from water. performed a number of experiments and studies to further support this, including following: vibrating sample magnetometer (VSM), Fourier transform infrared spectroscopy (FTIR), energy-dispersive X-ray photoelectron (XPS), scanning electron microscope (SEM), diffraction (XRD), Brunauer-Emmett-Teller surface area (BET). Our have determined that boasts considerable 868 m2/g with highest adsorption capacity (qmax) 942.12 mg/g. Study factors effect on process such as pH, TC concentration, dose, temperature. The isotherm fitted Langmuir equation, whereas kinetic pseudo-second-order equation. chemisorption well energy 20 kJ/mol. Adsorption thermodynamics indicated both endothermic spontaneous. As temperatures increased, amounts materials absorbed also increased. has properties it easily remove solution after process. five cycles high efficiency without change chemical composition XRD same before reusability. mechanism interaction between expected on: Electrostatic interaction, π-π hydrogen bonding, pore filling. results were optimized using Box Behnken-design (BBD).

Tetracycline (TC), a widely prescribed antibiotic to treat bacterial infections in humans and animals, poses substantial threat the environment due its extensive use. To address this issue, TiO2-based photocatalyst was employed for effective sonophotocatalytic degradation of TC. The ultrasound-driven TiO2 synthesis induced oxygen vacancies Ti3+ species, enhancing efficiency. formation confirmed by using various analytical techniques. synthesized with ultrasound (TiO2 US) demonstrates remarkable TC under halogen lamp irradiation, achieving an efficiency ∼96%, 1.56 times higher than that without WUS). Under diffuse sunlight, US WUS exhibit efficiencies 95 79%, respectively. Notably, effectively degraded hospital effluent, 83% This nanophotocatalyst displays appreciable reusability stability, offering promising solution efficiently degrading persistent emerging contaminants.
