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.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 0. 57 V,a maximum power density of 0. 28 m W/cm2 at 0. 44 V.
