Pt 29 Ru 51 P 15 particles with a uniform size distribution of 2 nm supported on multi‐walled carbon nanotubes (CNTs) have been prepared with the assistance of thioglycolic acid functionalization using NaH 2 PO 2 · H 2 O as a reducing agent. The Pt 29 Ru 51 P 15 /CNTs has been characterized by transmission electron microscopy (TEM), X‐ray diffraction (XRD), and X‐ray photoelectron spectroscopy (XPS). Its electrochemical properties have been examined by cyclic voltammetry (CV) and chronoamperometry (CA). The results show that Pt 29 Ru 51 P 15 /CNTs has a much narrower particle size distribution with no formation of aggregates, a greater electrochemically active surface area, and higher electrocatalytic activity for the electro‐oxidation of methanol
