摘要
We report a general method to graft aromatic molecules onto graphene thin film electrodes through a simple immersion process. Large-area electroactive graphene thin films grafted with methylene blue （MB） have been developed as electrocatalytic electrodes for the oxidation of β-nicotinamide adenine dinucleotide （NADH）. The oxidation of NADH starts from -0.08 V （vs. Ag/AgC1） at the graphene-MB thin film electrodes, showing a decrease of 530 mV in overpotential compared to a Ti metal electrode. The graphene-MB thin films have promising applications in biosensors and biofuel cells due to their ability to promote NADH electron transfer reaction.
我们向接枝汇报一个一般方法到 graphene 上，通过简单沉浸的薄电影电极处理的芳香的分子。大区域的 electroactive graphene 有甲又蓝色(MB ) 的薄电影 grafted 为菸碱腺嘌 dinucleotide (NADH ) 的氧化作为 electrocatalytic 电极被开发了。NADH 的氧化开始从 ? 0.08 V (对 Ag/AgCl ) 在 graphene-MB 薄电影电极，与一个 Ti 金属电极相比在过电位显示出 530 mV 的减少。薄电影有由于他们支持 NADH 电子转移反应的能力在生物传感器和 biofuel 房间答应应用程序的 graphene-MB。
