Implication

Tailored nitrogen-doped carbon enhances metal-support interaction to improve methanol oxidation in fuel cells, indicating better performance and stability.

Key Points

The study establishes a nitrogen-doping strategy to optimize methanol oxidation in direct methanol fuel cells.
Nitrogen configurations significantly improved metal-support interaction, yielding maximum 4687.5 mA mg−1Pt for Pt/NPC-900.
Tailored pyrolysis at 900°C produced a carrier with 56.7% pyridinic-N, enhancing platinum nanoparticle dispersion.
Raman spectroscopy revealed a non-CO pathway, reducing catalyst poisoning and ensuring long-term stability after 500 cycles.
