摘要

In this study, we are reporting the reaction mechanism for the photocatalytic response of graphite (Gr) intercalated tin oxide (SnO2) nanophotocatalysts. These nanocomposites were prepared using sonication method and characterized by using X-ray diffractometer (XRD), scanning electron microscopy (SEM), energy dispersive X-ray analysis (EDX), UV–Vis spectroscopy, photoluminescence (PL) spectroscopy, and Fourier transform infrared (FT-IR) spectroscopy. The XRD spectra confirmed average crystallite size of the order of 29 nm and the XRD patterns showed the presence of the tetragonal structure. Crystallite size was calculated using Debye–Scherrer’s and Williamson-Hall (WH) equations. The degradation of dye and photocatalytic response were optimized with tuning of various parameters such as ppm level of adsorbate and time response.
