摘要
CeO 2 improves the activity and selectivity of Pd/Al 2O 3 catalyst for methanol decomposition. The interaction between Pd and CeO 2 was then proposed to result in the promoting effect. The selectivity of CO and H 2 is significantly improved by addition of La 2O 3 to either Pd/Al 2O 3 or Pd/CeO 2/Al 2O 3 catalysts. Moreover, a synergistic promotion between CeO 2 and La 2O 3 on γ Al 2O 3 supported Pd catalysts was observed for the catalytic activity towards methanol decomposition into CO and H 2.
