摘要
Hierarchical cobalt dendrites with ferromagnetic properties have been synthesized by using the in situ produced cobalt carbonate together with cobalt oxalate as precursor and hypophosphite (H2PO2-) as the reducing agent in mixed solutions at 160 degrees C. XRD and SAED patterns reveal that the as-prepared cobalt dendrites have a single-crystalline structure with a [001] growth orientation. The shape evolution of the hierarchical cobalt dendrites was investigated. (C) 2008 Elsevier B.V. All rights reserved.
