摘要
We report here a fast procedure to modify glassy carbon (GC) electrode using commercially available unsubstituted cobalt phthalocyanine (COPC) and tetrasulfonated substituted nickel phthalocyanine (NiTSPc) simply adsorbed on oxidized single walled carbon nanotubes SWCNT. The electrocatalytic activity of the resulting SWCNT-MPc nanocomposite materials was evaluated toward the oxidation of two biologically relevant molecules, namely 2-mercaptoethanol (2-ME) and nitric oxide (NO). The obtained electrodes are highly stable under hydrodynamic conditions and the tailored hybrid surfaces allow enhancing electron transfer for the electrocatalytic oxidation of 2-ME and NO.
