Unprecedented electrochemical stabilization of platinum nanoparticles (PtNPs) is presented, upon insertion into shortened hollow graphitized carbon nanofibers (PtNP@S-GNF) toward the oxygen-reduction reaction for fuel-cell applications. In contrast to that observed for a commercial Pt/C electrocatalyst, the specific activity and the electrochemical surface area for PtNP@S-GNF remain practically unchanged during durability tests after 50 000 potential cycles, allowing the sustainable use of Pt.
