The High Photocatalytic Activity of SnO₂Nanoparticles Synthesized by Hydrothermal Method

Abstract

Tin oxide nanoparticles (SnO 2 NPs) were prepared at low temperature by hydrothermal method. Synthesized SnO 2 NPs were confirmed via characterization techniques such as UV-visible spectroscopy (UV-vis), X-ray diffraction (XRD), and Transmission Electron Microscope (TEM). The synthesized nanoparticles were in the size of 3 nm and they have high photocatalytic activity. The result showed that SnO 2 NPs degraded 88.88% MB solution after 30 minutes of UV illumination and reached 90.0% for 120 minutes (2 hours) of UV illumination. Moreover, they degraded 79.26% MB solution after 90 minutes (1.5 hours) under assisted sunlight illumination.
