Ternary NiCoPd nanocatalyst dispersed on multi-walled carbon nanotubes (CNTs), NiCoPd/CNTs, was synthesized using a simple and green sonochemical method. The as-prepared NiCoPd/CNT 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/CNT and CoPd/CNT, as well as monometallic Pd/CNT counterparts, which likely resulted from the synergistic function of the dopant metals of Ni and Co.
