以F127为模板剂,通过模板法制备了有序介孔炭材料(OMC)。对样品进行了X射线衍射(XRD),扫描电镜(SEM)和透射电镜(TEM),研究其结构和形貌。结果表明,OMC孔道有序规则,壁宽为10nm。电化学测试表明此电极材料具有良好的电化学性能,可逆性能好。在电流密度为700mA/g的条件下,经500次循环测试,有序介孔炭的容量保持率为90.5%。
Using the F127 as raw material, ordered mesoporous carbon (OMC) was synthesized by the template method. X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were used to study its structure and morphology. The results show that the OMC has ordered rules and the width of pore wall was 10nm. The electrochemical performance shows that this electrode material has good electrochemical performance and good reversibility. After 500 cycles, ordered mesoporous carbon has capaci tance retention rate of 90.5% at a current density of 700mA/g.
