摘　　要：在含Triton X-114的水相中制备了直径为2~3 nm的超细Au,Pt和Pd纳米线.纳米线修饰的玻碳电极具有极高的电化学活性面积.以商品Pt/C为阴极催化剂,分别以Au,Pt和Pd纳米线为阳极催化剂所构建的葡萄糖/氧气燃料电池在生理溶液中的最大输出功率密度为168,64和1.6μW·cm^-2.此外,Au纳米线比Pt或Pd纳米线作为阳极催化剂所构建的葡萄糖/氧气燃料电池具有更好的持久力.该研究为选择贵金属纳米线构建非酶葡萄糖传感器和燃料电池提供了重要的参考.Ultrathin Au,Pt and Pd nanowires（ NWs） with 2 - 3 nm diameter were prepared in aqueous phase in the presence of Triton X-114. The NWs modified glassy carbon electrodes showed ultrahigh electro-active surface areas. Glucose / O2 fuel cells were constructed with Au,Pt,and Pd NWs as anodic catalysts and commercial Pt / C as cathodic catalyst,which output maximum power density of 168,64,and 1. 6 μW·cm^- 2when operating in physiological solution,respectively. In addition,the glucose /O2 fuel cell with Au NWs as anodic catalyst showed durability higher than that with Pt or Pd NWs as anodic catalyst. This work may have important reference value in selecting noble metal nanowires for nonenzymatic glucose sensing and fuel cell constructions.
