摘要
We successfully fabricated a pair of microgap monolayer graphene electrodes (MMGEs), in which the basal planes of two monolayer graphenes are arranged in parallel facing each other across a small gap of 20 mu m, without using a microfabrication process. We measured the redox cycling in the MMGEs using (ferrocenylmethyl) trimethylammonium bromide and observed an excellent redox cycling under low-speed scanning conditions of 0.005 V/s. The collection efficiency reached 97% and was almost independent of the scan rate.
