Synthesis of Dy2Sn2O7-SnO2 nanocomposites via a new simple rout

In this investigation, Dy2Sn2O7-SnO2 nanocomposites prepared via a novel simple sol-gel rout. The effect of some preparation factors was studied to reach optimum condition. Results of this work illustrate that shape and size of the Dy2Sn2O7-SnO2 could be greatly influenced by these factors. The as-prepared Dy2Sn2O7-SnO2 nanocomposites were characterized by FT-IR, FESEM, EDS and XRD. According to the obtained results, it was found that with the aid of this new rout can be synthesized uniform sphere-like Dy2Sn2O7-SnO2 nanocomposites. The photocatalyst activity of as-obtained Dy2Sn2O7-SnO2 nanocomposites was also examined by degradation of the organic pollutant under ultraviolet light illumination.
