Abstract
Novel cobalt dendritic flowers have been successfully synthesized in high yield through a simple, facile, cost-effective solvothermal method. The products were characterized by X-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, and vibrating sample magnetometer techniques. The cobalt dendritic frames were composed of a main trunk and side branches covered by many flower-like petals. It was found that dosage of complex reagent, volume ratio of ethanol to water, and reaction time play important roles in controlling the resultant shapes. These cobalt dendritic flowers exhibit ferromagnetic behavior with a saturation magnetization of 154.1 emu/g and an enhanced coercivity up to 229 Oe, respectively, and are expected to have applications in both magnetoelectronic devices and catalysis.
