Characterization and electrocatalytic application of a fullerene/ionic-liquid composite

A fullerene/ionic-liquid composite was explored. Transmission Electron Microscopy (TEM) study showed that in the composite, C60 mainly exists as nano-clusters, Raman spectrum proved that the composite formed only by physical mix of C60 and 1-Butyl-3-methyl-imidazolium hexafluorophosphate (BMIPF6), the combination did not change the chemical naturation of C60. The electrochemical properties of the composite modified electrode, including the electrode reaction control function and the interfacial potential effect were studied. The results showed the electrode reaction is controlled by the diffusion and the interfacial potential can be ignored on the modified electrode. At the same time, the composite was found electrocatalytic property in the electrochemical oxidation of dihydronicotinamide adenine dinucleotide (NADH).
