Extremely Stable Platinum-Amorphous Carbon Electrocatalyst within Hollow Graphitized Carbon Nanofibers for the Oxygen Reduction Reaction
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.

Summary: | 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. |
