| Abstract: | The novel oxygen storage components were prepared and studied.It was proved that the new material has large surface area,high oxygen storage capacity and good performance of high-temperature-resistant.The active component-support interactions of Pd/Al2O3,Pd/OSZ and Pd/Al2O3+OSZ catalysts were studied via temperature programmed reduction(TPR) and temperature programmed desorption(TPD).The results show that the addition of novel oxygen storage components to the Pd/Al2O3 improves the thermal stability of Pd an... |
