Progress in Application of Hierarchical SnO_(2) in Gas Sensors

SnO_(2)由于具有制备方法简单、来源广泛、优异的n型半导体特性,被认为是制造气体传感器的理想候选材料。通过调整形态和改性对SnO_(2)基气体传感器的发展至关重要。由低维结构单元构筑的三维(3D)分级结构SnO_(2)基气体传感器取得了一定的成果。笔者简要综述了分级结构SnO_(2)的可控合成和改性方法,为制造新型高性能SnO_(2)基气体传感器提供新的思路和见解。

SnO_(2) is considered as an ideal candidate material for gas sensors due to its simple preparation method,wide range of sources and excellent n-type semiconductor properties.It is very important for the development of SnO_(2)-based gas sensor to adjust the morphology,size and composition.The threedimensional(3D)hierarchical SnO_(2)-based gas sensor constructed from low-dimensional elements has achieved some achievements.In this paper,controllable synthesis and modification methods of hierarchi⁃cal SnO_(2) are briefly reviewed,which provides new ideas and insights for manufacturing new highperformance SnO_(2)-based gas sensors.
