摘要
The present research aimed at investigating the electrocatalytic properties and the electrochemical deposition of Pt nanoparticles on carbon powder, carbon nanotube and preparation of carbon and single wall carbon nanotube supported platinum electrodes. The Pt nanoparticles were synthesized by electroreduction of hexachloroplatinic acid in aqueous solution at -200 mV Electrocatalytic properties of the modified electrodes for oxygen reduction were investigated by cyclic voltammetry in O-2 saturated solution containing 0.1 M HClO4. Methanol electrooxidation at the modified surfaces in 0.5 M HCLO4 was studied by cyclic voltammetry. The corresponding results showed that the Pt/SWCNT/GC electrode exhibits more improved catalytical activity than the Pt/C/GC electrode.
