摘　　要：本文以玫瑰花瓣为碳源,通过高温煅烧,获得三维多孔碳骨架材料。以水热法制备了CoO/三维玫瑰花碳骨架复合材料。材料的形貌和结构通过扫描电镜(SEM)、能谱仪(EDS)、红外光谱(FT-IR)来表征。采用循环伏安、恒流充放电来测试材料的电化学性能。实验结果显示,制备的复合材料具有分层、内部相通的孔结构;电化学测试表明复合材料有优异的电化学性能,当电流密度为20 m A/g时,比容量为328 F/g。Continuous 3D porous carbon skeleton was obtained by calcination with rose petal as raw material. Then,we utilized it as scaffold to prepare CoO / continuous 3D porous carbon skeleton of rose composite-based electrode for supercapacitor via hydrothermal method. The structure and morphology of the materials were characterized by Fourier Transform infrared spectroscopy（ FT-IR） and scanning electron microscopy（ SEM）. Meanwhile,the electrochemical performances of the samples were studied by cyclic voltammetry（ CV）,galvanostatic charge-discharge test. The results show that CoO /3D carbon skeleton of rose exhibits a high specific capacitance of 328 F/g at 20 mA/g.
