Abstract

In this study, tin oxide /reduced graphene oxide (SnO₂/rGO) samples were prepared by hydrothermal method. The structural characteristics, phase composition, morphology, and size of the samples were studied by X-ray diffraction, Raman scattering spectroscopy, and scanning electron microscopy. Results showed that SnO₂ nanoparticles had tetragonal rutile crystal structure with a size ranging from 4.65 nm to 5.77 nm when the pH was increased from 5 to 9. The SnO₂ nanoparticle morphology together with rGO layers was observed in the FESEM image of these samples. The absorption spectra of SnO₂/rGO samples show the characteristic absorption peak of SnO₂ at 296 nm, in which the band gap value of the material decreased from 3.91 eV to 3.81 eV when pH was increased from 5 to 9. The simultaneous formation of the two phases of SnO₂ and rGO was demonstrated by Raman scattering spectroscopy. Photocatalytic degradation of methylene blue reached 86% after 90 min under visible light.
