Iron Encapsulated within Pod‐like Carbon Nanotubes for Oxygen Reduction Reaction

Abstract

Chainmail for catalysts: A catalyst with iron nanoparticles confined inside pea-pod-like carbon nanotubes (see picture) exhibits a high activity and remarkable stability as a cathode catalyst in polymer electrolyte membrane fuel cells (PEMFC), even in presence of SO2. The approach offers a new route to electro- and heterogeneous catalysts for harsh conditions.
