Effect of the Support on the CO Oxidation Activity of Supported PdO Catalysts
Abstract:
The catalytic activities of the supported PdO catalysts were found to be dependent on the kind of the support as follows: CeO2 >ZrO2 >TiO2 >Al2O3 >SnO2 >ZSM-5 >SiO2. The reduction state of PdO in the catalyst played an important role in the oxidation activity of the catalyst. PdO/CeO2 was inferior to PdO/Al2O3 in heat-stability, but its activity for CO oxidation was higher than PdO/Al2O3, after it had been calcinated at 1200 ℃ for 4 h.
