Embedding Pt Nanocrystals in N-Doped Porous Carbon/Carbon Nanotubes toward Highly Stable Electrocatalysts for the Oxygen Reduction Reaction
Abstract
The development of highly stable and efficient catalysts for sluggish cathode oxygen reduction reaction (ORR) is extremely important for the long-term operation and the commercialization of proton exchange membrane fuel cells (PEMFCs) but still challenging. We present herein a facile strategy to efficiently embed Pt nanocrystals into N-doped porous carbon/carbon nanotubes (Pt@CN x /CNT). The N-doped porous carbon shells not only effectively prevented Pt nanocrystals from detachment, dissolution, migration, and aggregation during accelerated durability tests or heat-treatment at 900 °C, but also allowed the access of electrolyte to the Pt surface and preserved the good electron transfer of CNT by avoiding the structural damage of carbon nanotubes (CNTs). The interaction between the embedded Pt nanocrystals and the encapsulating CN x layer was found in Pt@CN x /CNT, which markedly affected the electronic structure of Pt nanocrystals and contributed to the improvement on the catalytic activity and stability of Pt@CN x /CNT. As a result, the Pt@CN x /CNT catalyst exhibited an excellent thermal stability, durability, and sufficient catalytic activity for ORR. The demonstrated strategy could be easily extended to produce a wide range of other electrocatalysts with even better activity and extraordinary stability.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
