Oxygen Reduction Activity of Vapor-Grown Platinum Nanotubes

The positive correlation between platinum crystallite size and specific activity for the oxygen reduction reaction has motivated an extensive search for functional catalyst structures that can rival the activity of polycrystalline Pt. One such class of catalysts, extended thin film electrocatalyst structures (ETFECS), make use of highaspect ratio morphologies to achieve high specific ORR activity while limiting sacrifices in electrochemical surface area (ECSA). Previously, electrochemical synthesis routes have been successfully used to make supportless ETFECS such as platinum nanotubes and nanowires.
