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.
Ultrafine Au, Pt and Pd nanowires 2 ~ 3 nm in diameter were prepared in an aqueous phase containing Triton X-114. The nanowire-modified glassy carbon electrode possessed a very high electrochemically active area.The Pt / C As the cathode catalyst, the maximum output power density of glucose / oxygen fuel cells in physiological solution with Au, Pt and Pd nanowires as anode catalysts were 168, 64 and 1.6 μW · cm-2 respectively. In addition, the Au nanowires Which has better durability than the glucose / oxygen fuel cell constructed by Pt or Pd nanowire as an anode catalyst.The research provides an important reference for the selection of non-enzymatic glucose sensor and fuel cell for selecting noble metal nanowires.
