A series of molybdenum carbide catalysts were prepared using 20%CH4-H2 to carburize molybdenum trioxide at different temperatures. The catalysts were characterized using X-ray diffraction, X-ray photoelectron spectroscopy and N2-adsorption. Their catalytic performance was evaluated in the model reaction of the dry-methane reforming to synthesis gas. Here, the characteration of bulk and surface Mo2C catalysts and its influence on the catalytic performance were described.
