摘要
(Graph Presented) Staying power: A new class of cathode catalysts based on supportless Pt (see picture, left) and PtPd nanotubes (NTs) is introduced. These materials have remarkable durability (right; CV = cyclic voltammetry, ECSA = electrochemical surface area) and high catalytic activity. They have the potential to circumvent most of the degradation pathways of current Pt/C and Pt-black catalysts. © 2007 Wiley-VCH Verlag GmbH & Co. KGaA.
