Nitrogen-Containing Carbon-Encapsulated Platinum Electrocatalysts Supported by Single-Walled Carbon Nanotubes for Polymer Electrolyte Fuel Cells.

ABSTRACT: Platinum (Pt)-based electrocatalysts are widely regarded as the preferred choice for oxygen reduction reaction (ORR) in Polymer Electrolyte Fuel Cell (PEFC). However, their low stability remains a critical challenge. To overcome this problem, high-crystallinity and high-purity single-walled carbon nanotubes (SWCNTs), fabricated by the enhanced direct injection pyrolysis synthesis (e-DIPS) method, are utilized as support with a nitrogen introducing treatment applied to produce nitrogen-containing SWCNT (N-SWCNT). Platinum electrocatalysts encapsulated by amorphous-carbon shell are synthesized on nitrogen-containing single-walled carbon nanotubes (Pt/N-SWCNT) using a facile and industrially favorable solution plasma (SP) method.
