Abstract

The high-quality Pt₄₈Ag₅₂ alloy nano-octahedra are synthesized via one-pot hydrothermal method. The catalytic growth of Ag⁰ atoms on Pt nuclei and selective oxidative etching on the Ag⁰ atoms contribute to the formation of alloy nano-octahedra. Pt₄₈Ag₅₂ alloy nano-octahedra show excellent electrocatalytic activity and durability for the methanol oxidation reaction (MOR).
