Abstract

In this work Dy2Ti2O7 nanoparticles (DTONPs) were prepared through a sol-gel procedure using different surfactants, and the effects of the various solvents and surfactants (e.g. cetyltrimethylammonium bromide, sodium dodecyl sulfate, and glucose) on the size, morphology, and crystal structure of the DTONPs was evaluated. The different characterizations of the nanostructures were performed using X-ray diffraction, scanning electron microscopy, diffuse reflectance spectroscopy (UV-Vis), and Fourier transform infrared spectroscopy. The vibrating sample magnetometery analyses of the samples reveal a ferromagnetic behavior under ambient conditions. Eventually the photo-catalytic behavior of the DTONPs in the UV-induced degradation of methyl orange as organic pollutant in water in water was evaluated under UV light irradiation. The results showed that methylene blue degradation was about 88 and 96 for two DTONPs after 50 min, so the synthesized product can be used as an effective photocatalyst.
