Abstract:

An eletrodeposition of random arrays of Pt nanoparticles, supported on glassy carbon electrode (GCE), is reported. It has been shown that such arrays exhibited good catalytic activity with respect to methanol oxidation in an acidic medium and longer deposition time produced more Pt nanoparticles on GCE leading to larger effective catalytic area and higher catalytic current. It was found that the process of methanol oxidation was controlled by the diffusion of methanol and the Pt nanoparticles formed stable film on GCE surface and also exhibited stable catalytic performance towards methanol oxidation.
