An efficient way of immobilizing and wiring a large amount of laccase on non-covalently-functionalized multi-walled carbon nanotube (MWCNT) electrodes is reported. 1-(2-anthraquinonylaminomethyl)pyrene and 1-[bis(2-anthraquinonyl)aminomethyl]pyrene were synthesized and studied for their capability to non-covalently functionalize MWCNT electrodes and immobilize and orientate laccase on the nanostructured electrodes. This led to high-performance biocathodes for oxygen reduction by direct electron transfer with maximum current densities of (1±0.2) mA cm(-2). The performance of the resulting bioelectrodes could be doubled simply by using the bis-anthraquinone compound. The bioelectrodes show excellent stability over weeks and can thus be envisioned in enzymatic biofuel cells.
报道了一种将大量漆酶固定在非共价功能化多壁碳纳米管（MWCNT）电极上的有效方法。合成了 1-(2-蒽醌基氨甲基)蒽和 1-[双(2-蒽醌基)氨甲基]蒽，研究了它们将 MWCNT 电极非共价功能化以及将漆酶固定和定向在纳米结构电极上的能力。这导致了高性能的生物阴极，通过直接电子转移实现了氧还原，最大电流密度为（1±0.2）mA cm(-2)。通过使用双蒽醌化合物，所得生物电极的性能可以简单地提高一倍。这些生物电极在数周内表现出优异的稳定性，因此可以在酶生物燃料电池中得到应用。
