We report on the fabrication and measurement of devices designed to study the electrochemical behavior of individual monolayer graphene sheets as electrodes. We have examined both mechanically exfoliated and chemical vapor deposited (CVD) graphene.

The effective device areas, determined from cyclic voltammetric measurements, show good agreement with the geometric area of the graphene sheets, indicating that the redox reactions occur on clean graphene surfaces. The electron transfer rates of ferrocenemethanol at both types of graphene electrodes were found to be more than 10-fold faster than at the basal plane of bulk graphite, which we ascribe to corrugations in the graphene sheets. We further describe an electrochemical investigation of adsorptive phenomena on graphene surfaces. Our results show that electrochemistry can provide a powerful means of investigating the interactions between molecules and the surfaces of graphene sheets as electrodes.

Prime Minister Shinzo Abe, Prince Fumihito and his wife, Princess Kiko, attended the event along with about 870 people affected by the disaster, including family members of the dead. Bereaved family members representing each of the three hardest-hit prefectures of Miyagi, Iwate and Fukushima spoke about their experiences at the ceremony. Fumihito, in his address, expressed concern about the physical and mental health of the elderly and other evacuees as their evacuation is prolonged.

Abe said his government will “push to build a Japan resilient to natural disasters” while touching on the lifting of evacuation orders for municipalities struck by the Fukushima nuclear accident as progress over the past year.
