Fabrication of carbon nanotube supported molybdenum carbide catalyst and electrochemical oxidation properties

Carbon nanotube supported molybdenum carbide catalysts were prepared as a function of various preparation conditions and characterized, and their catalytic activities were compared through electrochemical oxidation of methanol. To overcome the low activity of a transition metal catalyst, carbon nanotube was used as a support, and the amount and the kind of precursors, acid treatment method, and carburization temperature were varied for the catalyst preparation. ICP-AES, XRD and TEM were used for the catalyst characterization. Based on the various preparation methods of carbon nanotube supported molybdenum carbide catalysts (M02C/CNT), the size and the amount of supported catalysts could be controlled, and their effects on the electrochemical oxidation could be explained
