摘要：

(Figure Presented) Hollow nan': Hollow face-centered cubic (fcc) Co nanoparallelepipeds were prepared by thermolysis of solid fcc CoO nanoparallelepipeds in oleylamine (see TEM image). The solid fcc CoO nanoparallelepipeds are reduced by the oleylamine surfactant to form hollow fcc Co nanoparallelepipeds. Voids and fcc Co are generated on the surface of the solid fcc CoO nanoparallelepipeds by the removal of oxide as carbon monoxide. © 2008 Wiley-VCH Verlag GmbH & Co. KGaA.
