摘要：

High and mighty: Octahedral SnO 2 particles bound by high-index {332} facets were synthesized by a simple hydrothermal route using SnCl 2·5 H 2O as the tin salt with the assistance of hydrochloric acid and poly(vinylpyrrolidone). These particles show excellent selective gas sensing performance because they have large numbers of dangling bonds on their surfaces. Copyright © 2012 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
