Ternary NiCoPd nanocatalyst dispersed on multiwalled carbon nanotubes (CNTs), NiCoPd/CNTs, was synthesized using a simple and green sonochemical method. The as-prepared NiCoPd/CNTs hybrids were characterized by transmission electron microscopy (TEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and inductively coupled plasma-atomic emission spectrometry (ICP-AES). The electrochemical measurements revealed that the ternary NiCoPd/CNTs exhibited an enhanced electrocatalytic activity for the methanol oxidation reaction (MOR), much superior to those of the binary NiPd/CNTs and CoPd/CNTs, as well as mono-metallic Pd/CNTs counterparts, which likely resulted from the synergistic function of the dopant metals of Ni and Co.
