The effects of FePO4PtC nanocomposites on the electrocatalytic properties were examined after 1000 accelerated cycles (up to 1.48V vs normal hydrogen electrode). The FePO4PtC nanocomposites exhibited similar electrocatalytic properties to PtC without any initial degradation, and also showed enhanced long-term stabilities. By optimizing the synthetic conditions of FePO4PtC 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.
