Mesoporous molecular sieve SBA-16 supported bimetallic carbide catalyst Ni--Mo2C/SBA-16 was prepared using the impregnation and thermal decomposition method. N2 adsorption-desorption isotherms, powder X-ray diffraction, and transmission electron microscopy measurements show that the active components wereuniformly dispersed on the support, and the catalyst still remained ordered mesoporous structure of SBA-16. Catalytic performance measurements show that the catalyst exhibitedhigher conversion rate of CH4, CO2, and selectivityof CO, H2, and remarkable anti-coke effect.
