摘要：

The effects of FePO4-Pt/C nanocomposites on the electrocatalytic properties were examined after 1000 accelerated cycles (up to 1.48 V 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.
