Synthesis of hierarchical Sn3O4 microflowers self-assembled by nanosheets

In this paper, hierarchical Sn3O4 microflowers self-assembled by nanosheets were successfully synthesized via a simple one-pot hydrothermal route. The crystalline phase and morphology of the as-prepared sample were characterized using X-ray diffraction, field-emission scanning electron microscope and transmission electron microscope. UV-vis absorbance and Raman scattering behavior of the Sn3O4 microflowers were also investigated. Electronic density of states calculation using DFT method revealed that the upper valance band of Sn3O4 was dominated by O 2p. (C) 2014 Elsevier B.V. All rights reserved.
