[In-situ IR study of adsorption and decomposition of methanol on gamma-Al2O3, CeO2 and their supported Pd catalysts].
The adsorption and decomposition of methanol on gamma-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/Al2O2 catalyst. A synergistic effect between Pd and CeO2 on the activity of Pd/CeO2 catalyst for methanol decomposition was proved.
