【摘要】 采用水热法制备了多壁碳纳米管(MCNTs)。以X射线衍射、透射电子显微镜等手段对所制碳纳米管进行了表征:管直径在50 nm左右,长度多为5~20μm,管壁厚度一般不超过10nm。电化学测试表明碳纳米管的放电容量约为398mAh.g-1,相当于1.5%的储氢量。更多还原

【Abstract】 Multi-walled carbon nanotubes(MCNTs) with an average diameter of 5nm were prepared by hydrothermal method.The MCNTs were characterized by XRD and TEM.Electrochemical measurements showed the discharging capacity of carbon nanotubes was up to 398 mAh·g-1(corresponding to 1.5% hydrogen storage).更多还原
