Cobalt Nanoskeletons: One‐Pot Solution Synthesis of Cubic Cobalt Nanoskeletons (Adv. Mater. 16/2009)

Cubic Co nanoskeletons with an edge length of 100 nm can be prepared by a facile one-step solution method. In work reported on p. 1636 by Ying Ma, Fangli Yuan, Jiannian Yao, and co-workers, CoO nanoparticles of ∼10 nm are subjected to self-aggregating, in situ reduction, Ostwald ripening, and facet-selective coordination-assisted etching to form these novel structures, which exhibit excellent magnetic properties. Simple control of the shape can be achieved by altering the reaction time.
