中文摘要：

利用多孔聚碳酸酯膜，采用两步模板电沉积法制备了铂／普鲁士蓝（Pt／PB）复合纳米线。将Pt／PB复合纳米线固定在玻碳（GC）电极上，构建过氧化氢电化学传感器。实验结果表明，Pt／PB复合纳米线对过氧化氢的还原有良好的电催化作用。在电位为-0．1V时，响应电流信号与过氧化氢浓度呈良好的线性关系，线性范围为6．1×10^-4～1．8×10^-2mol／L，检出限（S／N=3）为5．0×10^-7mol／L。该修饰电极具有响应速率快、稳定性高、使用寿命长等优点，同时还具有一定的抗干扰能力。

英文摘要：

Composite platinum and prussian blue（Pt/PB） nanowires were fabricated using a two-step template electrodeposition method, in which polycarbonate membrane （PC） template was used for altering electrolyte solutions. The composite Pt/PB nanowires were immobilized onto glassy carbon（GC） electrode to develop an electrochemical sensing platform for hydrogen peroxide detection. Experimental results showed that Pt/PB composite nanowires had a good electrical catalyst effect on the reduction of hydrogen peroxide. Amperometric signals showed a linear correlation to hydrogen peroxide concentration in the range from 6. 1 × 10-4 mol/L to 1. 8 × 10-2 mol/L at the applied potential of - 0. 1 V, with a detection limit of 5. 0 × 10-7 mol/L（S/N= 3）. The modified electrode has a fast response rate, high stability, long life, as well as some anti-jamming capability.
