【Abstract】 A template-free route without adjusting the pH value of the system was suggested to synthesize self-assembled one-dimensional Co₃O₄ at room temperature.XRD,SEM,vibrating sample magnetometer（VSM） and cyclic voltammogram were used to investigate the crystal structure,morphologies,magnetic and electrical properties. Results show that the products are in pure cubic Co₃O₄ phase with a space group of Fd3m（227）.The morphologies of all the synthesized samples are self-assembled nanorods or nanowires.The obtained Co₃O₄ shows paramagnetism at room temperature and good capacitive behavior in cyclic voltammetry curves.The influences of sintering temperature and sodium dodecyl sulfate（SDS） on the morphologies were also studied.更多还原
