摘要
A series of materials Ce0.3+xZr0.6-xY0.1O1.95 were prepared by co-precipitation routine and the property of these materials was studied by means of oxygen storage capacity, temperature programming reduction, X-ray diffraction, transmission electronic microscope, and X-ray photoelectron spectroscopy. The results indicate that the materials with a low Ce/Zr molar ratio possess higher cerium atom utilization ratio, reducibility and thermal stability than the materials with a high Ce/Zr ratio, and Ce0.35Zr0.55Y0.1O1.95 possesses the best properties.
