英文摘要Molybdenum carbide catalysts were successfully prepared using three types of carbon materials as supports and carbon sources (carburizers) by the hydrogen or carbothermal reduction method. The results of X-ray diffraction and temperature-programmed reduction-mass spectroscopy showed that the nature of the carbon materials and synthetic conditions influenced the formation of molybdenum carbide. The molybdenum species could be reduced to metallic molybdenum over the graphitic carbon (carbon black) material in hydrogen atmosphere, and then the metallic molybdenum was carbonized directly by carbon to molybdenum carbide. The formation temperature for molybdenum carbide over carbon nanotubes was lower than that over carbon black. Under the condition of hydrogen insufficiency or inert gas, the molybdenum species was reduced and carbonized by carbon to molybdenum carbide at above 700 degrees C.
