摘要 以碳纳米管为模板合成CNT/FeNi复合纳米材料,用X-射线粉末衍射(XRD)和透射电镜(TEM)对CNT/FeNi复合纳米材料的物相和形貌进行表征,用循环伏安法研究了CNT/FeNi复合纳米材料的电化学过程.结果表明:其电化学过程为电化学步骤控制的不可逆过程;随着pH增大,还原峰的峰电位发生负移,峰电流增大,质子参加电极过程且参加反应的质子数与转移的电子数之比为0.5. CNT/FeNi nanocomposites were synthesized using carbon nanotubes as templates.X-ray powder diffraction(XRD)and Transmission electron microscopy(TEM)were used to characterize the phase and morphology of CNT/FeNi nanocomposites.The electrochemical process of the glassy carbon electrode modified showed that,the electrochemical process is a irreverssible process controlled by electrochemical step,with the increase of the value of pH,the reduction potential moves to negative and the reduction current increases,proton joins the electrochemical process and the ratio of the number of the proton and the electron translated during the process is 0.5.
