| Summary: | The purpose of this work was to explore the efficacy of tin oxide (SnO2) with reduced graphene oxide (r-GO) Nanocomposites (NCs) in terms of their photocatalytic activity. The preparation of pure r-GO sheets and SnO2/r-GO NCs was accomplished by the use of the one-pot green method. Several imaging and spectroscopic methods, including as X-ray diffraction (XRD), photoluminescence (PL), UV–Vis spectroscopy, Fourier transform infrared (FTIR), transmission electron microscopy (TEM), and Raman scattering microscopy, were used in order to describe the materials that were synthesized. Following the addition of r-GO, the crystallite size of the SnO2 nanoparticles increased. Using transmission electron microscopy, it was discovered that the SnO2 nanoparticles were securely linked to the r-GO sheets. According to the results of the optical experiments, the bandgap energy of the SnO2/r-GO NCs was slightly lower when compared to the energy of the pure r-GO sheet. After r-GO doping, the PL spectra of the SnO2/r-GO NCs were found to be less intense compared to those of pure r-GO. This indicates that the recombination rate of the surface charges (e−/h+) reduced. The results of this study indicate that the degrading efficiency of SnO2/r-GO NCs was nearly twice as high as that of methyl orange (MO) dye, which was 99%. This is in comparison to the 95% efficiency of pure r-GO. A unique strategy for enhancing the photocatalytic effectiveness of SnO2 nanoparticles is suggested in this study. This strategy involves fusing graphene derivatives with SnO2 nanoparticles. |
