Abstract
Tin oxide nanoparticles (size = 14 nm) have been prepared using DNA, a biological molecule, by co-precipitation method. The SnO2 catalysts were characterized by X-ray diffraction, scanning electron microscope, transmission electron spectroscopy, fourier transform infra-red spectroscopy, photoluminescence spectroscopy and UV–Vis spectroscopy. The photocatalytic properties of SnO2 nanoparticles were investigated via methyl orange as a model organic compound under UV light irradiation. The study proves SnO2 as an efficient catalyst in removing organic pollutants in water.
