摘要：

Novel hierarchical flower-like SnO2 (HFL-SnO2) nanostructures are successfully synthesized through the hydrothermal method. We find that the hierarchical architectures of SnO2 is assembled by a number of regular-shaped nanosheets, which are cross-linked in the interior of the micro-flower. The product also has a high specific surface area of about 78.8 m(2) g(-1). Based on the nucleation and self-assembly process, a possible formation mechanism is proposed. The effects of SDS and NaCl on the product are also studied. Moreover, the product exhibits excellent photocatalytic activity and take possession of good stability and reusability under visible light. This study provides valuable experimental data for further study of nanomaterials and their photocatalytic properties. (C) 2017 Published by Elsevier B.V.
