| Description |
Pt@Pd/C nanoparticle was prepared by the galvanic displacement reaction between Pt4รพ
and Pd. A simple synthesis strategy was followed to prepare carbon-supported Pd nanostructure.
Pt modified Pd nanostructure on carbon was characterized by transmission
electron microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, Cyclic Voltammetry
and Linear Sweep Voltammetry. Pt@Pd/C electro-catalyst exhibited higher catalytic
activity toward oxygen reduction reaction with excellent methanol tolerance than Pt/C.
Pt@Pd/C catalyst showed consistent catalytic activity before and after the durability study.
Higher methanol tolerance of Pt@Pd/C with less Pt content than Pt/C suggests that it could
be a potential alternative cathode electro-catalyst for DMFCs
