Abstract: Surface oxygen species of Pd catalysts on different supports were investigated by O2-TPD-MS, TPR techniques. It was found that as a support. TiO2 showed better desorption and regeneration ability of surface oxygen than Al2O3 and CeO2. The reducibility of Pd catalyst was found to be in cerrespondence with its surface oxygen departure.

Key words: supported Pd catalyst, oxygen species
