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.

This study reports fabrication of graphene-titanium dioxide (G-TiO2) nanocomposites with varying graphene content (0%, 25%, 50%, and 75%) through a sonication-assisted co-precipitation method. The synthesized materials were analyzed FTIR, DRS, SEM, XRD techniques, which confirmed the successful formation an anatase-phase TiO2 tetragonal structure crystallite sizes ranging from 10 to 25 nm after calcination at 600 °C for 4 h. addition resulted in significant reduction bandgap energy 3.2 eV 1.55 eV, enhancing material's absorption visible-light spectrum. nanocomposite 50% loading exhibited strong adsorption highest photocatalytic efficiency, achieving 98.29% degradation cationic methylene blue dye under irradiation. exceptional performance is attributed synergistic effects graphene, including improved light absorption, enhanced charge carrier separation, increased electron transfer efficiency. Kinetic analysis revealed that followed pseudo-first-order reaction kinetics. Furthermore, recycling tests demonstrated structural stability reusability (up 5 cycles) nanocomposite, indicating its potential as effective photocatalyst environmental applications. effectiveness G-TiO2 mitigating industrial pollutants also underscores significance approach.

Abstract This study investigates ZnO/TiO 2 nanocomposites synthesized by the sol–gel method for their potential application in textile wastewater treatment. The physicochemical properties of these materials were comprehensively characterized using various analytical techniques, including transmission electron microscopy (TEM), x-ray diffraction (XRD) analysis, fluorescence (XRF) spectroscopy, Brunauer–Emmett–Teller (BET) surface area and UV–visible (UV-Vis) spectroscopy. XRD XRF analyses confirmed formation a heterostructure. TEM images revealed quasi-spherical morphology with slight agglomeration. nanocomposite 1:5 molar ratio Zn(II):Ti(IV) showed highest BET (91.345 m g −1 ) narrowest band gap (Eg = 3.06 eV). composite demonstrated efficient degradation methylene blue dye under sunlight irradiation exhibited 100% antibacterial activity against S. typhi aureus at concentrations ≥5 mg ml , indicating its treating wastewater.
