Fe-N-C Boosts the Stability of Supported Platinum Nanoparticles for Fuel Cells

Fei Xiao et al.

Summary: This study found that Pt/Fe-N-C has better electrochemical surface area retention compared to conventional high-surface-area carbon. In situ studies revealed that the Pt dissolution rate of Pt/Fe-N-C is 3 times smaller than that of Pt/C during cycling. Density functional theory calculations further demonstrated that Fe-N-C can provide stable support and alleviate oxide formation. This finding emphasizes the importance of carbon support selection for achieving a more durable Pt-based electrocatalyst.
