Hydrothermal synthesis and characterization of novel Sn2O3 hierarchical nanostructures

•Novel Sn2O3 hierarchical nanostructures were fabricated by the hydrothermal method.•The as-prepared Sn2O3 products can transform into SnO2 by calcinations.•The possible reaction of generating Sn2O3 is discussed.

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 °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 °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.
