英文摘要	通讯作者地址: Wang, ZC; Nonspherical hollow nanoparticles (NHNPs) have attracted a great deal of attention in recent years due to their unique properties and many promising applications. However, compared to hollow spheres, the fabrication of NHNPs is generally much more difficult and there are only a few successful examples to date. In this work, X-shaped hollow alpha-FeOOH penetration twins were first synthesized by a facile hydrothermal reaction. X-shaped alpha-Fe2O3 hollow nanostructures with high-index {11 (2) over bar3} facets exposed were further obtained via the topotactic transformation of alpha-FeOOH precursor. To the best of our knowledge, this is the first report on the nanostructures with high-index facets as well as a hollow interior. Owing to the special hollow structure and the high-energy surface, the as-obtained alpha-Fe2O3 nanocrystals show excellent visible-light photocatalytic activity toward the degradation of RhB.; State Key Development Program for Basic Research of China 2007CB935603 National Natural Science Foundation of China 51372212
