Abstract
The electrochemical oxidation of nicotinamide adenine dinucleotide (NADH) is studied systematically on four types of electrodes, i.e., glassy carbon (GC), carbon (C), Au nanoparticles (AuNP), and C-supported AuNP (AuNP/C) in a 0.05Â M phosphate buffer solution (pH 7.4) before and after the electrochemical pretreatment carried out by repetitive potential scanning between â0.2Â V and 1.0Â V (vs. SCE) for 100 cycles. This simple pretreatment improves the electrocatalytic activity of the AuNP/C toward the NADH oxidation remarkably, suggesting the key role of Au oxide layers in facilitating the NADH electrochemical oxidation.
