Description
Summary:1-Methoxy 5-methylphenazinium methyl sulphate (1-MeO-PMS) was adsorbed on the disk plane of a plastic formed carbon (PFC) rod electrode (3 mm in diameter). PFC is a novel carbon material prepared by mixing various amounts of pure graphite with an organic binder and pyrolyzing to "glassy carbon" at moderate final temperatures of 1000–1400 ℃. The prepared 1-MeO-PMS/PFC electrode exhibited a sufficient electrocatalytic activity for dihydronicotinamide adenine dinucleotide (NADH) oxidation. At an applied potential of −0.05 V vs Ag/AgCl at pH 7.0, the 1-MeO-PMS/PFC electrode showed a fast (
