摘　　要：一维纳米材料具有高比表面积,表现出很多奇特的物理和化学性能,因此一维纳米材料的合成和性质引起了人们的广泛关注。目前,合成一维纳米氧化物的方法很多,如模板法合成一维纳米铁氧体、水热法合成γ-MnOOH纳米棒.A template-free route without adjusting the pH value of the system was suggested to synthesize self-assembled one-dimensional Co_3O_4 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 Co_3O_4 phase with a space group of Fd3m（227）.The morphologies of all the synthesized samples are self-assembled nanorods or nanowires.The obtained Co_3O_4 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.
