Green synthesis of SnO2 nanoparticles and its photocatalytic activity of phenolsulfonphthalein dye

•Persia Americana seed extract was utilized for the production of colloidal SnO2 NPs.•Nanoparticles were in the size of 4 nm.•Photocatalytic property was done with phenolsulfonphthalein dye.

Tin oxide (SnO2) nanoparticles were prepared using Persia Americana seed methanolic extract by calcining stannous chloride precursors at 300–500 °C by green synthesis method. Synthesized SnO2 NPs were confirmed via characterization techniques such as UV–visible spectroscopy (UV), X-ray diffraction (XRD), Scanning Electron Microscope (SEM) and Energy Dispersive X-ray analysis (EDAX). The results of characterization technique states that the synthesized nanoparticles were in the size of 4 nm and further we have undergone catalytic degradation of organic dye named phenolsulfonphthalein (phenol red). The result showed that SnO2 NPs shows much degradation activity by the catalytic action of long UV exactly at 365 nm.
