摘要：
Phosphorus-doped multiwalled carbon nanotubes (P-MCNTs) were synthesized by thermolysis and employed as supports to prepare Pt/P-MCNTs catalyst for direct methanol fuel cells (DMFCs). Pt/P-MCNTs exhibited much higher electrocatalytic activity and longer-term stability for methanol oxidation than Pt/MCNTs in acidic medium, due to the higher dispersion and utilization rate and the improvement of intrinsic activity for methanol oxidation of Pt nanoparticles, indicating a highly potential application of Pt/P-MCNTs in DMFCs.
