摘要：

Dendritic cobalt nanocrystals have been synthesized by the reduction of Co2+ with hydrazine hydrate in ethanol via a room temperature solution synthetic route. The magnetic coercivity H-c of as-prepared cobalt dendrites came up to 500 Oe at room temperature. We chose different solvents to control the phases and morphologies of the cobalt products.
