Novel self-assembled highly hierarchical SnO nanoflowers with acute edge petals have been successfully synthesized by a template-free hydrothermal growth method using SnCl2 center dot 2H(2)O and KOH as precursors. Field emission scanning electron microscopy results show that the flower-like SnO architectureis in the range 4-7 mu m. Furthermore, Raman modes at A(1g) = 212 and B-1g = 114 cm(-1) further testify to the existence of nanotetragonal phase SnO. The electrochemical results suggest that synthesized SnO nanoflowers are a promising anode material for lithium ion batteries. (c) 2012 Acta Materialia Inc. Published by Elsevier Ltd.
