Abstract

Two different substrates, GC and graphite electrodes, have been coated with electrodeposited Pt nanoparticles (PtNPs) of different morphologies and sizes (from 2 mm to 20 nm). The electrochem. behavior of the platinised GC electrodes has been mainly evaluated in terms of the increase of the real surface area. A nickel-based hydrotalcite-like compd. (HT) has been electrosynthesised on the GC platinised electrodes, by the cathodic redn. of a 0.03 M Ni and Al nitrates soln., and the cyclic voltammetric responses to these electrodes have been measured in a 0.1 M NaOH soln. Finally, the electrocatalytic performances of the GC-PtNPs-HT electrodes to ethanol and glucose have been investigated and compared with the performances of HT electrodeposited onto bare Pt, in the same conditions.
