| 摘 要： | 使用葡萄糖糖氧化酶(GOD)和漆酶(Lac)分别做酶生物燃料电池的阳极与阴极,构成了GOD/Lac酶生物燃料电池.首先通过循环伏安法研究了酶生物燃料电池阳极催化剂GOD和阴极催化剂Lac在碳布基底电极上的直接电化学行为,结果表明:GOD与Lac在该修饰电极上均完成了一个直接、可逆的电化学过程,保持了自身的生物学活性,为成功构成GOD/Lac酶生物燃料电池提供一个必要条件.其二,采用葡萄糖作为GOD/Lac酶生物燃料电池的阳极燃料,氧气(O2)作为GOD/Lac酶生物燃料电池的阴极燃料,使用充放电仪测得该GOD/Lac酶生物燃料电池在38.5 mV处的最大输出功率密度为0.108μW·cm-2,电流密度为2.75uμA·cm-2.

| Abstract: | In this article,the GOD/ Lac biofuel cell are fabricated by glucose oxidase(GOD) anode and laccase(Lac) cathode respectively.Firstly,the direct electrochemical behavior of anodic catalyst GOD and cathodal catalyst Lac on carbon cloth electrode are described by circulation voltammetry.The experimental results indicate that both GOD and Lac have had direct quasi-reversible electrochemical process and their biologic activity can been retained.All of these can provide a necessary condition for building the GOD/... |
