The High Photocatalytic Activity of SnO2 Nanoparticles Synthesized by Hydrothermal Method

Tin oxide nanoparticles (SnO2 NPs) were prepared at low temperature by hydrothermal method. Synthesized SnO2 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 SnO2 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.
