Effective wastewater treatment is essential due to the dye environmental threats. Photocatalysis offers an eco-friendly degradation solution. Herein, we report a double Z-scheme photocatalyst, i.e. LaFeO3/Boron-doped g-C3N4/Fe2O3 (LFO/B-CN/FO), fabricated via hydrothermal method. The formation of this ternary system supported by structural, surface, and morphological analyses. Differential scanning calorimetry thermal gravimetric analysis demonstrated crystallization behavior composite. Because synergetic effects in composite boron doping, optical band gap energy reduced 1.6 eV. Under visible light irradiation, LFO/B-CN/FO nanocomposite degraded navy-blue 98% 130 min at neutral pH, surpassing CN, B-CN, binary composites B-CN with LFO FO. process was rationalized using pseudo-first- pseudo-second-order kinetic models, which confirmed high catalytic efficiency. heterojunction enhanced absorption, charge separation, carrier lifetime, hence improving photocatalytic activity. Overall, as-fabricated outperformed reference catalysts terms chemical reactivity, characteristics, electrical performance. This work opens up new route for design fabrication photocatalysts potential renewable applications.

Water pollution by synthetic dyes, particularly acid black 1, poses a significant environmental challenge. The present study has addressed this issue synthesizing novel magnesium oxide (MgO) nanocomposites using extracts from Padina sanctae crucis (Psc) and Sargassum hystrix (Sh) algae via sol-gel process. primary objective was to evaluate the efficacy of these in removing 1 dye aqueous solutions. synthesized materials were characterized Fourier transform infrared spectroscopy (FT-IR), energy dispersive X-ray (EDS), scanning electron microscopy (SEM), diffraction (XRD), Brunauer-Emmett-Teller (BET) analysis, thermal gravimetric analysis (TGA), dynamic light scattering (DLS). results show successful synthesis MgONPs MgO@Sh MgO@Psc NPs with approximate sizes 45.64–65.64, 52.14–59.09 39.19–58.30 nm. Batch mode experiments conducted assess influence contact time, pH, adsorbent dosage on removal efficiency. demonstrated that at pH 6, increasing 0.5 2 g/L enhanced efficiency 41.6% 59.1% for 43.4% 64.1% MgO@Sh. Sips isotherm model intra-particle diffusion kinetic provided best fit experimental data. negative values ΔG° indicated, which adsorption process is more spontaneous higher temperatures. This highlights potential as effective adsorbents removal, offering promising solution water purification.

This study involved the synthesis of magnetite nanoparticles by co-precipitation method. The synthesized were subsequently evaluated for their catalytic efficacy in degradation and ozonation tartrazine dye (TTD), employing sodium persulfate as a catalyst both presence absence ozone. material characterization revealed that Fe3O4 proven to have crystalline structure XRD. While spherical agglomerates with flower-like morphology SEM, similarly FT-IR detected Fe – O H bond vibrations, boosting surface area activity. TTD was assessed laboratory-scale reactor, its progress monitored using UV-visible spectrophotometry. A comparative analysis two methods demonstrated superior compared degradation, achieving maximum 94.35% within 25 min contact time. Optimal parameters included concentration 50 ppm, dosage 0.75 g, 8 mm, ozone inlet 5 g/L at pH 3. Evaluation kinetics indicated second-order model most appropriate, suggesting physicochemical nature removal process. Furthermore, demonstrates enhanced efficiency decomposition conventional methods.
