| 摘 要： | 通过油胺(Oleylamine)还原法制备了金纳米线(Au nanowires),将其与酸化处理的多壁碳纳米管(MWCNTs)通过层层组装制备了Au nanowires-MWCNTs复合结构修饰的玻碳电极(Au nanowires-MWCNTs/GCE).电化学研究结果表明,与单纯Au nanowires或MWCNTs修饰电极相比,Au nanowires-MWCNTs/GCE对葡萄糖表现出更优良的电催化性能.以Au nanowires-MWCNTs/GCE为阳极,电沉积Pt膜电极(Pt/GCE)为阴极,构建了葡萄糖/O2燃料电池.测试结果表明,构建的燃料电池的开路电位(OCP)为0.57 V,在0.44 V下最大功率密度(Pmax)为0.28 m W/cm2.

| Abstract: | One-dimensional gold nanowires were prepared using oleylamine as reducing agent, and were assembled with carboxylic multi-walled carbon nanotubes( MWCNTs) through electrostatic adsorption to form a layer-by-layer assembled Au nanowires-MWCNTs on the glassy carbon electrode( GCE) to be used as catalyst for the oxidation of glucose. Electrochemical research results showed that the Au nanowires-MWCNTs/GCE electrode displayed higher catalytic properties than the simple Au nanowires or MWCNTs modified electrode towards the oxidation of glucose. Therefore, a new type of glucose fuel cell was elaborately assembled using Au nanowires-MWCNTs/GCE as the anode and platinum membrane/GCE as the cathod, which showed an open circuit-potential of 057 V, a maximum power density of 028 mW/cm2 at 044 V. |
