Photocatalytic processes offer promising solutions for environmental remediation and clean energy production, yet their efficiency under the visible light spectrum remains a significant challenge. Here, we report novel silver–graphene (Ag-G) modified TiO2 (Ag-G-TiO2) nanocomposite photocatalyst that demonstrates remarkably enhanced photocatalytic activity both dye wastewater degradation hydrogen production UV irradiation. Through comprehensive characterization performance analysis, reveal Ag-G modification narrows bandgap from 3.12 eV to 1.79 eV, enabling efficient absorption. The achieves peak rate of 191 μmolesg−1h−1 in deionized (DI) water solution light, significantly outperforming unmodified TiO2. Intriguingly, observe an inverse relationship between rates with tap versus DI water, highlighting critical role composition processes. This work not only advances understanding fundamental mechanisms but also presents solar-driven production. Ag-G-TiO2 nanocomposite’s across spectra, coupled its dual functionality evolution, represents step towards addressing challenges treatment sustainable generation. Our findings highlight complex interplay absorption reaction conditions, offering new insights optimizing systems. research paves way developing more versatile photocatalysts, potentially contributing global transition technologies circular economy waste management

In our endeavor to improve the efficiency of Fenton-like process for degradation levofloxacin (LVX), a comprehensive study was conducted on applicability heterogeneous catalyst: iron-containing silica pillared clay (Fe-SPC). Optimization experiments showed that an optimal and cost-effective Fe content 10 wt% significantly improved catalyst efficiency. A characterization, determine porous properties, chemical composition, morphological visual appearance, highlighted special features compared raw clay. When investigating effects operating parameters adsorptive oxidative it found optimum conditions were 0.5 g/L Fe-SPC at pH 3 40 °C using 500 mg/L hydrogen peroxide (H2O2). This resulted in impressive average removal 90% from 50 LVX solution after 180 min least 5 consecutive runs without additional treatment. Scavenging total organic carbon tests confirmed involvement hydroxyl radicals formation intermediates prior complete mineralization.
