Ni based mesoporous Al2O3 catalysts were prepared by evaporation-induced self-assembly (EISA) method, and were employed as catalyst in combined methane dry reforming (DRM) and methane partial oxidization (POM) reaction. The catalysts were characterized by transmission electron micrographs (TEM), N-2 physical adsorption desorption, H-2 chemisorption and temperature programmed reduction (H-2-TPR), X-ray diffraction (XRD) and Raman spectroscopy. The TEM and N-2-physisorption characterization showed that the catalysts had typical mesoporous structure. The catalytic activity tests results indicated that the catalysts prepared by the one-pot method had better catalytic performance for combined methane dry reforming and methane partial oxidation reaction. The TEM and Raman analysis of used catalysts showed that combined DRM with POM could effectively suppress the formation of carbon on catalysts surface.
