title = "Oxygen reduction reaction on platinum/tantalum oxide electrocatalysts for PEM fuel cells",
abstract = "Three synthetic routes are evaluated to obtain highly dispersed platinum on tantalum oxide supported catalysts: a) deposition of platinum colloids on tantalum oxide followed by mechanical grinding with Vulcan carbon; b) deposition of tantalum oxide on Vulcan carbon, followed by the deposition of platinum colloids; and c) deposition of Pt colloids on Vulcan carbon, followed by deposition of tantalum oxide. Specific activities for oxygen reduction reaction at 0.9V are a factor of two higher for catalysts synthesized via preparation routes a and b compared to Pt/VC. In comparison, the activity of catalysts synthesized via route c is close to that of Pt/VC. Mass activities for the catalysts possessing high specific activities are lower than for Pt/VC due to their low electrochemically available platinum surface area.",
