Supportless Pt and PtPd Nanotubes as Electrocatalysts for Oxygen‐Reduction Reactions

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.
