Driven by global environmental concerns, great efforts are currently made to develop novel, cheap and practical means for producing highly efficient electrocatalysts, specifically for the low-temperature fuel-cell applications. Employing an old but yet unexplored method based on electrochemical dispergation of platinum by the alternating current, we show that the freshly prepared Pt/C catalysts exhibit greatly enhanced catalytic activity (up to 350% for oxygen reduction and up to 200% for ethylene glycol oxidation) as compared with that of a commercially available counterpart (E-TEK). A key role in these reactions is attributed to a specific nanoparticle morphology. These findings should provide a revival of an ancient but simple and efficient electrochemical process and motivate further researches in the field.
