Pt@Pd/C nanoparticle was prepared by the galvanic displacement reaction between Pt4+ 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.
► A simple strategy for tuning ORR activity of Pd/C. ► Pt encapsulated Pd/C preparation by galvanic replacement reaction. ► Durable Pt@Pd/C electro-catalyst with enhanced ORR activity and methanol tolerance.
