Environmental benign synthesis of tin oxide (SnO2) nanoparticles using Actinidia deliciosa (Kiwi) peel extract with enhanced catalytic properties

The study deals with the biological exploration of tin oxide (SnO2) nanoparticles with the aid of Actinidia deliciosa (Kiwi) peel extract. The synthesized SnO2 nanoparticle exhibits a UV-visible absorption spectrum at around 290 nm. The phytoconstituents present in Actinidia deliciosa (Kiwi) peel extract act as a reducing and capping mediator was probed using Fourier transform infrared spectroscopy (FTIR). The morphological analysis of the synthesized nanoparticles was analyzed using scanning electron microscopy (SEM) and transmission electron microscopy (TEM) showed the nanoparticles were spherical with the size ranging from 5 to 10 nm. The chemical purity of the nanoparticles was analyzed using EDX analysis. Further, the catalytic efficiency of the synthesized SnO2 nanoparticles was examined for Methylene blue (MB), Methyl orange (MO), and Rhodamine B (RhB) dyes. The results exhibit the nanoparticles act as an efficient catalyst for the degradation of textile dyes in 8 min, 8 min, and 6 min with the degradation efficiency of 89%, 87%, and 97%. Hence the fabricated SnO2 nanoparticles with reduced size showed enhanced catalytic activity towards degradation of several textile dyes. Hence from the obtained results it was scrutinized that the synthesized SnO2 nanoparticles exhibit excellent catalytic activity in short time at room temperature and it remains constant for several cycles. So the synthesized SnO2 nanoparticles act a potent candidate for the degradation of anthropogenic pollutants.
