新型FePt石墨纳米囊的合成及其作为甲醇燃料电池催化剂性能的应用

In this work, we synthesized a graphene encapsulated FePt nanoparticle (G-FePt) through a simple one-step CVD method. The G-FePt is stable and size controllable. This nanoparticle integrated the excellent catalysis ability of noble metal with the superior electronic properties of graphene. After comprehensive characterization such as TEM, XRD, its electrocatalytic performance and stability were investigated in the methanol oxidation model using cyclic voltammetry. The G-FePt showed very good catalytic capacity and stability, which makes it a promising candidate for the future fuel cell catalyst development.
