ITO electrode was modified by Pd-based electrospun nanonbers followed by calcining precursor in air and nitrogen conditions. SEM was used to measure morphology of the modified electrodes. The electrochemical behavior of the modified electrodes was investigated compared to that of Pt microelectrode (25|un in diameter). The results showed that they have electrochemical behavior of microelectrode, but the modified electrodes with quite low limit of detection possess higher electrochemical response signal and signaloise ratio than those of single Pt microelectrode.%应用静电纺丝法制备纳米纤维修饰电极,之后分别在空气和N2环境下煅烧制备Pd纳米粒子微阵列修饰的ITO电极.应用SEM对电极表面形貌进行了表征.应用循环伏安法对修饰电极的电化学行为进行研究,并与直径是25μm的Pt微电极进行了比对,结果证明,它们都具有微米电极的电化学行为,但修饰电极的信号值远高于单根Pt微电极,具有较高的信噪比和极低的检出限.
