Photocatalytic studies of tin oxide nanostructures produced by different methods

Abstract

This paper reports the photocatalytic behavior of tin oxide (SnO2) nanostructures prepared via three different aqueous solution-processed techniques: Precipitation, hydrothermal, and laser ablation. The prepared SnO2 nanostructures were characterized by X-ray diffraction (XRD) and field electron scanning electron microscopy (SEM). The photocatalytic activity was evaluated by the oxidative degradation of rhodamine blue (RhB) under visible light. The SnO2 nanostructure prepared by the laser ablation method exhibit significantly improved photocatalytic activity toward RhB due to the size and morphology of the prepared nanostructure.
