Chemisorption combined with IR spectrometry and TPD and microreactor techniques have been used to investigate the adsorption activation and partial oxidation reactivity of CO₂ and CO₂H₆ on title catalyst. It is found that CO₂H₆ is chemisorbed on the surface of the catalyst through H of its C-H bond and terminal O of Mo=O bond. For the adsorption of CO₂ on the catalyst besides the linear type and the scissors type there appears another horizo-ntal type. The lattice oxygen of the catalyst is found to play an important role in partial oxidation. A mechanism of partial oxidation is proposed.
- CO₂ activation,
- ethane oxidation,
- complex oxide support,
- bimetallic Pd-Cu catalyst
