In this study, tin oxide (SnO2) nanoparticles were synthesized via a green route using jujube fruit as a
non-toxic, renewable reducing agent, and excellent stabilizer. The biosynthesized SnO2 nanoparticles
were characterized by X-ray diffraction analysis (XRD), Fourier-Transform infrared (FT-IR), scanning electron
microscopy (SEM) and energy dispersive X-ray spectroscopy (EDX). Moreover, the photocatalytic
activity of the novel SnO2 nanoparticles was investigated for degradation of two organic dyes which were
named methylene blue (MB) and eriochrome black-T (EBT) under direct sunlight. An excellent performance
was observed and about 90% and 83% of degradation efficiencies were achieved for MB and
EBT, respectively. The high stability of the photocatalyst also makes SnO2 nanoparticles easily to reuse
at least four times without any remarkable loss in activity.
