摘要：
We report the successful synthesis of novel Sn2O3 with hierarchical 3D nanostructures via a facile hydrothermal method for the first time. The as-prepared Sn2O3 products transform into SnO2 after calcinations (800 degrees C) and a simultaneous TGA and DSC analysis of the as-prepared Sn2O3 sample determines that the main increment of mass takes place in the temperature range 534-800 degrees C. The well-defined nanostructures are composed of thin nanosheets. The growth mechanisms are also discussed by observing the morphology revolution at various reaction times. Furthermore, the oxidation states of the Sn2O3 hierarchical nanostructures are confirmed by the shape analysis of corresponding XPS O 1s and Sn 3d peaks using the decomposition procedure.
