Highly Enhanced Methanol Electrooxidation on Pt/N-CNT-Decorated FeP**

The electrooxidation of methanol - the anodic reaction of direct methanol fuel cells - suffers from slow kinetics. Here, we report an enhanced current density for a Pt catalyst supported on nitrogen-doped carbon nanotube (N-CNT) decorated FeP. X-ray photoelectron spectra show that the introduction of FeP increases the binding energy of the Pt nanoparticles. The results show that Pt/FeP15%/N-CNT displays a 3.4 times higher forward peak current density compared to commercial Pt/C. The improved performance is attributed to a change in the electronic state of the Pt nanoparticles through the electronic interaction between Pt and FeP, evidenced by the mitigated CO poisoning.

Automated summary

The study found that supporting Pt catalyst on FeP-decorated N-CNT can enhance the forward peak current density, showing 3.4 times higher than commercial Pt/C. The improved performance is attributed to the change in electronic state of Pt nanoparticles through the electronic interaction between Pt and FeP, which mitigates CO poisoning.
