Abstract The cyclic voltammetric (CV) behaviors of NAD + were studied with a multi‐walled carbon nanotubes (MWNTs) modified glassy carbon (GC) electrode. In 0.05 mol/L tris(hydroxymethyl)aminomethane‐HCl (Tris‐HCl) buffer solution (pH=6.9), the MWNTs modified electrode showed high electrocatalytic activity toward reduction of NAD + . The electroreduction of NAD + was an irreversible diffusion controlled process. The cathodic peak current in‐creased linearly with increasing the concentration of NAD + . The influences of scan rate, temperature and concentration were also investigated.
