Abstract：The adsorption and decomposition of methanol on γ-Al2O3 and CeO2 supports，and Pd／Al2O3 and Pd/CeO2 catalysts were studied by in-situ FTIR technique. The possible pathway of methanol decomposition on Pd／Al2O3 and Pd/CeO2 catalysts was analyzed according to the interaction of Pd and the supports. Methanol was dehydrogenated into DME or decomposed towards CO and H2 over different active phase on Pd／Al2O3 catalyst. A synergistic effect between Pd and CeO2 on the activity of Pd／CeO2 catalyst for methanol decomposition was proved.
