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.

The S-Scheme heterojunction design offers a promising pathway to enhance the photocatalytic activity of semiconductors for antibiotic degradation in aquatic environments. Graphitic carbon nitride (g-C3N4) stands out due its robust visible light absorption, exceptional charge separation efficiency, and abundant active sites, rendering it an ideal candidate sustainable energy-efficient photocatalysis. This review delves into potential g-C3N4-based heterojunctions degradation, with particular emphasis on principles, inherent advantages, application prospects. We discuss various semiconductor materials, including metal oxides, multicomponent magnetic sulfides, which can be paired g-C3N4 fabricate heterojunctions. Furthermore, we explore common preparation techniques synthesizing composites, such as hydrothermal method, solvothermal calcination self-assembly situ growth, etc. Additionally, summarize applications these antibiotics, focusing specifically quinolones tetracyclines. By providing insights development heterojunctions, actively contribute ongoing exploration innovative technologies field degradation. Our findings underscore vast addressing challenge contamination water sources.
