摘要：
The core-shell Al/Co nanocomposites with sheet-like and spherical Co nanocrystals as shells were fabricated via a displacement reaction between At and CoCl2 center dot 6H(2)O in a glycol solution by the controlling feeding rate of NH4F glycol solution. By eroding the At core in HCl aquatic solution, hollow spherical nanostructures assembled by sheet-like and spherical Co nanocrystals were obtained. The possible mechanism for the formation of Co hollow nanostructures composed of different shaped nanocrystals has been discussed. (C) 2009 Elsevier B.V. All rights reserved.
