Title: Synthesis, characterization, and gas-sensing properties of monodispersed SnO{sub 2} nanocubes

Monodispersed single-crystalline SnO{sub 2} nanocubes with exposed a large percentage of high-energy surfaces have been synthesized by a simple solvothermal process at low temperature without any templates and catalysts. The as-prepared samples have been characterized by X-ray diffraction and transmission electron microscopy. Many outstanding characters of the final products have been shown, such as uniform particle size, high purity, and monodispersity. In property, superior gas-sensing properties such as high response, rapid response-recovery time, and good selectivity have also been shown to ethanol at an optimal working temperature of as low as 280 °C. It indicates that the as-prepared SnO{sub 2} nanocubes are promising for gas sensors.
