The CuPtPd catalyst is designed and synthesized successfully via directly reducing metal ions. The composition, morphology, and structure of the as-prepared CuPtPd nanohybrids are characterized by scanning electron microscopy and transmission electron microscopy, energy-dispersive spectrometry, selected-area electron diffraction, X-ray diffraction, and inductively coupled plasma atomic emission spectrometry. By comparison of the electrocatalytic properties of the ternary CuPtPd catalyst with bimetallic catalysts, we find that ternary nanocomposites perform better electrocatalytic and antipoisoning activity toward oxidation of methanol. The catalytic mass activity of the CuPtPd nanoparticles is 5.51-fold of commercial Pd black and 12.1-fold of Pt black.
