Abstract

One-dimensional SnO 2/V 2O 5 core–shell nanowires were synthesized by a combination of hydrothermal and wet chemical routes at room temperature. The photocatalytic behavior of the SnO 2/V 2O 5 nanowires for the photodegradation of toluidine blue “O” dye (TBO) under UV exposure was examined. SnO 2/V 2O 5 showed better photocatalytic activity than V 2O 5 nanowires and bulk. The significant enhancement of the photocatalytic activity of the core–shell SnO 2/V 2O 5 nanowires was attributed mainly to its large specific surface area and efficient charge separation at the SnO 2/V 2O 5 photocatalyst interface.
