Iron-phosphate∕platinum∕carbon nanocomposites for enhanced electrocatalytic stability

Abstract

The effects of FePO4–Pt∕C nanocomposites on the electrocatalytic properties were examined after 1000 accelerated cycles (up to 1.48V vs normal hydrogen electrode). The FePO4–Pt∕C nanocomposites exhibited similar electrocatalytic properties to Pt∕C without any initial degradation, and also showed enhanced long-term stabilities. By optimizing the synthetic conditions of FePO4–Pt∕C nanocomposites, the well-dispersed FePO4 nanoparticles played important roles in preserving the Pt surface activities, by preventing both the dissolution and agglomeration of Pt nanoparticles.
