摘　　要：By using the combination of solvothermal and microemulsion methods, hierarchical cobalt nanorods with 70 nm width and 39 mm length have been prepared under mild conditions. The nanorods are composed of a bundle of 20 nm wide whiskers, which are composed of spherical nanoparticles（\{5 nm\}）. It is suggested that the co-operation of the reduction of Co 2+ and the transition from spherical \{micelles\} into hexagonal rod-like micelles lead to the formation of the nanostructured cobalt filaments.By using the combination of solvothermal and microemulsion methods, hierarchical cobalt nanorods with 70 nm width and 3_9 mm length have been prepared under mild conditions.
