Using sunlight as the driving force for photocatalytic processes holds great promise sustainability. As a starting point developing material capable of degrading aquatic pollutants using solar energy stimulus, this work focuses on synthesizing Au-TiO2 nanocomposites deposition-precipitation method. Characterization nanoparticles was performed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and Transmission Electron Microscopy (TEM). A model pollutant, paracetamol, used to test synergetic effect Au (0.05 wt%) (NPs) with TiO2 activity. The influence parameters pH, loading (0.4, 0.8, 1 g/L), pollutant concentration (20, 30, 40 ppm), contact time (30, 60, 90, 120, 150, 180 min) studied exposing NPs radiation. degradation most effective at 3 h, an initial 20 ppm, pH 6.8. Under these conditions, paracetamol in g/L can be degraded more than 99.17% under irradiation. result composite's ability successfully serve photocatalyst sun radiation, water purification widespread, cost-effective, environmentally friendly.

Advanced photocatalytic materials for environmental cleanup need to be developed in response growing concerns about water pollution. This paper presents a novel N-doped hollow carbon spheres (NHCSs)-supported Co2SnO4/WS2 heterostructure synthesized using hydrothermal approach and examined various characterization techniques evaluate the crystal structures, functional groups, surface morphology, chemical properties, optical characteristics. The performance of Co2SnO4/WS2@NHCSs composite was assessed by degrading Congo red (CR) under visible light, resulting notable degradation rate 87.22% 60 min. enhanced efficiency is ascribed Z-scheme heterojunction charge-transfer mechanism, which augments sustained charge separation while suppressing recombination visible-light irradiation. Furthermore, quenching experiments revealed that specific superoxide radicals (•O2-) hydroxyl (•OH) were integral reaction, potential pathway mechanism effective photocatalysts also suggested. suggested LC-MS analysis. study highlights promise composites practical wastewater treatment applications, providing sustainable solution remediation.
