分级纳米结构不仅具有低维纳米构成基元的特征，还具备较大的比表面积及特别的空间孔道结构，从而表现出不同于单一构成基元的独特的物理、化学性质。综述了近年来SnO 2分级纳米结构的研究进展，重点介绍了球状、花状、枝棒状等SnO 2分级纳米结构的合成方法、形貌及气敏性能，并对SnO 2分级纳米结构作为高性能气敏材料的应用和发展前景进行了展望。

Hierarchical nanostructures combining the features of low-dimensional nanoscale building blocks, the higher specific surface area and particular pore spatial structures show unique physical and chemical properties different from those of the mono-morphological nanostructures. The research progress on the SnO2 hierarchical nanostructure in recent years is reviewed, which is focused on the synthesis methods, morphologies and gas-sensing properties of the spherical, flower-like and branch-rod-like SnO 2 hierarchical nanostructures. Some prospects and suggestions of the application and development of SnO2 nanomaterials with hierarchical structure as high performance gas sensing materials are proposed.
