Electrochemical properties of carbon nanodiscs

Carbon nanodiscs are new bottom-up prepared nanomaterials with well-defined diameter and thickness (of 1-2 mu m and 20-50 nm, respectively). We investigate their electrochemical performance towards oxidation and reduction of small inorganic molecules as well as biomarkers. We have found that carbon nanodiscs exhibit faster observable heterogeneous electron transfer rates than graphite. However, this can be due to nanographitic impurities within the nanodiscs sample.
