摘　　要：在微波加热条件下,无机碳化物SiC与Cl2反应,通过去除碳化物的非碳原子来制备骨架炭(CDC),采用XRD、SEM、HRTEM等检测方法,对制备的骨架炭进行了表征,研究了其电容特性。结果表明:CDC具有较低的电阻率,较高的振实密度,质量比电容量为170F/g,体积比电容量为110F/cm3,是一种性能优良的双电层电容器的电极材料。By microwave heating, the SiC reacted with chlorine through removal of non-carbon atoms from SiC, carbide-derived carbons were obtained, XRD 、 SEM and HRTEM were employed for the characterizations of CDC. The results show that the resistivity of SiC-CDC is low, while its tap density is high, The gravimetric specific capacitance can reach 170F/g and the volumetric specific capacitance can reach 110 F/cm^3. SiC-CDC is a promising material with good performance for electric double layer capacitors,
