Fabrication of SnO2/NGO hybrid nanocomposite as an effective photocatalyst for binary dye degradation under sunlight illumination

We successfully synthesized nitrogen-doped graphene oxide grafting tin oxide nanoparticles (SnO2/NGO nanocomposite). To evaluate the surface, optical and morphology characterization of synthesized SnO2/NGO nanocomposites was done using various analytical techniques. The XRD data indicate the crystallinity of a high-purity SnO2/NGO nanocomposite in nature. The Raman spectra of the resultant SnO2/NGO nanocomposite exhibit moderate graphitization with a ID/IG intensity of 0.98. Under sunlight irradiation, the photocatalytic activity of a produced SnO2/NGO nanocomposite on the breakdown of toxic binary organic dyes (methylene blue/methyl orange) was examined. On MB and MO, the resultant SnO2/NGO nanocomposite had a maximum degradation efficiency of 150 mins and 89.4%, 93.7%, respectively. Furthermore, the simple and inexpensive hydrothermalderived SnO2/NGO nanocomposite exhibits rapid photocatalytic degradation on MB and MO when exposed to sunlight illumination.
