A mesoporous silica (SBA-15) was used to prepare the Ni/Mo2C catalysts in order to study the influence of the support on the catalytic performance. The catalysts were characterized by-N2adsorption, X-ray diffraction, FT-IR absorption, CO2-TPD and SEM analysis. The catalytic properties was tested at 800°C, atmospheric pressure, GHSV of 9000 ml3h-1g-1and a CH4/CO2molar ratio of 1. These results suggest that catalytic activity, which is directly related to the incorporation of nickel and molybdenum carbide to the mesoporous silica.
