本研究以单壁碳纳米管（SWNTs）修饰的碳纤维微电极（CFMEs）为基础，构建了一种新型的微型葡萄糖/O2生物燃料电池（BFCs）。单壁碳纳米管被用作载体以稳定地限制电催化剂（即，亚甲基绿色，MG）用于氧化NADH和阳极生物催化剂（即，NAD+依赖性葡萄糖脱氢酶，GDH）用于葡萄糖的氧化和用于有效促进阴极生物催化剂的直接电化学（即，漆酶）进行O2还原。所制备的微米级GDH基生物阳极和漆酶基生物阴极分别对葡萄糖的氧化和氧气的还原具有良好的生物电催化活性。在含有10 mM NAD+和45 mM葡萄糖的0.10M磷酸盐缓冲液中，组装的微型无隔室葡萄糖/O2 BFC在0.40V下的功率密度达到58μWcm− 2。并对微型葡萄糖/O_2BFC的稳定性进行了评价。
This study demonstrates a new kind of miniature glucose/O2biofuel cells (BFCs) based on carbon fiber microelectrodes (CFMEs) modified with single-walled carbon nanotubes (SWNTs). SWNTs are used as a support both for stably confining the electrocatalyst (i.e., methylene green, MG) for the oxidation of NADH and the anodic biocatalyst (i.e., NAD+-dependent glucose dehydrogenase, GDH) for the oxidation of glucose and for efficiently facilitating direct electrochemistry of the cathodic biocatalyst (i.e., laccase) for the O2reduction. The prepared micro-sized GDH-based bioanode and laccase-based biocathode exhibit good bioelectrocatalytic activity toward the oxidation of glucose and the reduction of oxygen, respectively. In 0.10M phosphate buffer containing 10mM NAD+and 45mM glucose under ambient air, the power density of the assembled miniature compartment-less glucose/O2BFC reaches 58μWcm−2at 0.40V. The stability of the miniature glucose/O2BFC is also evaluated.
