One-dimensional (1D) semiconducting oxide nanostructures such as ZnO, SnO2, and In2O3 have been extensively studied due to their excellent optical and electrical properties. Growth of 1D nanostructures with precisely controlled size, phase purity, crystallinity, and chemical composition still presents numerous challenges. In this review, we report the recent progress on the synthesis of binary oxide nanostructures consisting of different oxides through a simple and effective vapor transport approach in our research. By controlling the experimental conditions, this approach enables the synthesis of various multicomponent binary oxide nanowires.
