In this work, molybdenum carbide (Mo2C) nanoparticles on multiwalled carbon nanotube (WMCNT) were synthesized by using a microwave-assisted solid-state carburization. The structure, morphology and physicochemical properties were studied by different techniques such as X-ray diffraction (XRD), transmission electron microscopy (TEM) and energy dispersive spectroscopy (EDS). The obtained samples were used as catalyst supports for methanol oxidation of fuel cells. The electrochemical properties of the catalysts were characterized by different methods, e.g., cyclic voltammetry (CV), chronoamperometry (CA), etc. As compared to the conventional Pt/C electrocatalyst, the Pt/Mo2C-MWCNT shows much higher eletrocatalytic activity and much better stability. The as-prepared MO2C/MWCNT materials are promising alternatives as catalyst supports for application in fuel cells and the newly developed methodology, microwave-assisted solid-state carburization is a very promising technique for preparing nanocomposite materials.
