Fabrication of Graphene-Based Tin Oxide (Sno2) Composite With Improved Visible Light For The Photocatalytic Degradation of Methylene Blue

The SnO2 nanoparticles were synthesized via the co-precipitation method by varying weight percentages (1%, 2%, 3% and 4%) of GO loaded on the SnO2 nanoparticles. The effect of varied composition of GO on the SnO2/GO nanocomposite were investigated using spectroscopic instruments such as Scanning Electron Microscope (SEM), Transmission electron microscope (TEM), X-ray diffraction (XRD), Element mapping, Energy Dispersive X-Ray Spectroscopy (EDX), the Fourier transform infrared spectroscopy (FT-IR), Brunauer-Emmett-Teller (BET), photoluminescence (PL), the Ultraviolet–visible spectroscopy (UV-Vis) and Diffuse reflectance spectrum (DRS) showed the successful formation of GO/SnO2 nanostructures. furthermore, the photocatalytic activity of the GO/SnO2 nanocomposites and SnO2 were studied through the photodegradation of methylene blue under visible light irradiation. The degradation efficiencies of the GO/SnO2 were much higher than that of pure SnO2. From the results obtained, we believe that this current work will provide relevant views for further fabrication of other novel nanostructures and exploration of their applications.
