In this investigation, for the first time, berry leaf extract was used for green synthesis of tin oxide (SnO2) nanoparticles. In this method, the flavonoids in berry leaf extract are responsible for reduction of metal ions and their conversion to nanoparticles. The nanoparticles were synthesized in green conditions and no toxic or organic solvents were used during the synthesis of nanoparticles. After identifying the synthesized nanoparticles using X-Ray diffraction (XRD), their morphology was determined using transmission electron microscopy (TEM). Then, the photocatalytic activity of SnO2 nanoparticles for degradation of organic dyes including blue bromothymol, green bromocrozole and methylene blue was investigated using Ultraviolet–visible (UV) spectroscopy under direct sunlight and without the use of any toxic reducing agent. The results show that SnO2 nanoparticles are able to degrade organic dyes at high efficiency and short duration. The recyclability of SnO2 nanoparticles in degradation of methylene blue was also investigated, and the results showed a high recyclability for the SnO2 nanoparticles.
