Abstract Hybrid wastewater treatment systems offer viable solutions to enhance the removal of complicated contaminants from aqueous system. This innovation has opened new avenues for advanced processes. Herein, a novel TiO 2 –ZnO functionalized coal fly ash-based ceramic membrane was fabricated by utilizing combined pressing and sintering method. The intrinsic properties membranes were characterized their chemical physical such as stability, mechanical water absorption, porosity established. shape, crystallinity, thermal characteristics, functional groups present also determined using SEM, XRD, TGA, FTIR studies, respectively. results showed that with 0.5 g sintered at 850 °C exhibited best thermal, possessed required ultrafiltration applications. Photocatalytic degradation tetracycline (TC) model pollutant examined optimum efficiency 77% achieved within 100 min visible irradiation membrane. Moreso, found be stable 73% after 5 consecutive cycles reusability study, showing negligible loss efficiency. scale-up photocatalytic utilization in real industrial applications will confirm robustness.

Visible-Light Activation of Persulfate by Nano-Fe/Tio2 Photocatalyst Towards Efficient Degradation of Acid Orange Dye

Опубликована: Янв. 1, 2025

Titanium oxide (TiO2) semiconducting materials attracted great interest in photocatalytic degradation of organic pollutants the treatment textile wastewater recent days. The present study focuses on a sol-gel method for synthesizing nano-Fe doped TiO2 photocatalyst, and employs advanced oxidation technique termed activation persulfate to degrade azo dye. performance targeted degradant acid orange dye (AO7) was analyzed regarding impacts PDS concentration, solution pH, catalyst dose. Results showed that under visible light irradiation, removal rate AO7 can reach peak 98.40% within 40 min at an optimal initial concentration 0.05 g·L-1, pH 5, 4 mM, dosage 0.4 accompanied by reaction constant 0.1152 min-1. Moreover, higher activity nano-Fe/TiO2 comparison pure is attributed specific surface area, smaller crystalline size, reduced band gap (2.54 eV), increased efficiency electron-hole generation according SEM, XRD, FTIR DRS characterization measurements. persisted robustly after runs. mechanism revealed radical (·SO4-) hole (h+) followed superoxide radicals (·O2-) played crucial role providing better irradiation. outcomes demonstrate future possibilities applying photocatalyst light.
