Single-walled carbon nanohorns (SWNHs), a new type of carbon nanomaterials, possess excellent catalytic properties, high-purity, and low toxicities, which make them suitable for bioelectrochemical application. Here a biofuel cell anode has been developed by using SWNHs as the support for redox mediator and biocatalyst for the first time. Cyclic voltammetric results show SWNHs promotes the electropolymerization of methylene blue (MB) and the resulted nanocomposite (poly MB-SWNHs) exhibits prominent catalytic ability to the oxidation of nicotinamide adenine dinucleotide. Glucose dehydrogenase was then immobilized on the poly MB-SWNHs modified electrode for the oxidation of glucose. Employing Pt nanoparticles supported on functionalized TiO(2) colloidal spheres with nanoporous surface as cathode catalyst, the as-assembled glucose/O(2) biofuel cell operate at the physiological condition with good performance.
单壁碳纳米角（SWNHs）是一种新型的碳纳米材料，具有优异的催化性能、高纯度和低毒性，非常适合生物电化学应用。本文首次将 SWNHs 用作氧化还原介体的载体和生物催化剂，用于制备生物燃料电池的阳极。循环伏安结果表明，SWNHs 能够促进亚甲蓝（MB）的电聚合，所得纳米复合材料（聚 MB-SWNHs）对烟酰胺腺嘌呤二核苷酸的氧化具有显著的催化能力。然后，将葡萄糖脱氢酶固定在聚 MB-SWNHs 修饰的电极上，以氧化葡萄糖。采用具有纳米多孔表面的功能化 TiO2 胶体球负载的 Pt 纳米粒子作为阴极催化剂，组装的葡萄糖/O2 生物燃料电池在生理条件下具有良好的性能。
