Preparation, characterization, and electrocatalytic performance of graphene-methylene blue thin films
Graphene, electrocatalysis, methylene blue, β-nicotinamide adenine dinucleotide (NADH)
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/AgCl) 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.
