  The influence of precipitation temperature on the properties of ceria–zirconia solid solution composites

  摘要：

  The ceria-zirconia composites (CZ) with a Ce/Zr mass ratio of 1/1 were synthesized by a back-titration method, in which the influence of precipitation temperature on the properties of ceria-zirconia precipitates was investigated. The resulting precipitation and mixed oxides at different precipitation temperatures were then characterized by a range of techniques, including textural properties, X-ray diffraction (XRD), Raman spectroscopy, scanning electron microscope (SEM), X-ray photoelectron spectroscopy (XPS), H-2-temperature programmed reduction (H-2-TPR) as well as oxygen storage capacity (OSC) measurement. The results revealed that ceria-zirconia composites were formed as solid solution and such structure is favored of thermostability and texture properties. In particular, the composite CZ-70 synthesized at 70 degrees C exhibited prominent thermostability with a surface area of 32 m(2)/g as well as a pore volume of 0.15 cc/g after aging treatment at 1000 degrees C for 5 h. And this was found to be associated with the wider pore size distribution which maybe owed to the formation of large crystal at the primary stage of precipitation. Additionally, the composite CZ-70 showed excellent reduction property and OSC benefiting from stable texture and structure. (C) 2014 Elsevier B.V. All rights reserved.

  Three types of Ce0.45Zr0.45La0.1O1.95 mixed oxides were prepared by H2O2-assisted precipitation using ZrOCO3, ZrO(NO3)(2), and Zr(NO3)(4) as precursors. The Pd/Ce0.45Zr0.45La0.1O1.95 three-way catalysts were prepared by the wet impregnation and characterized by the X-ray diffraction (XRD), Raman spectroscopy, nitrogen adsorption, X-ray photoelectron spectroscopy (XPS), temperature-programmed reduction (TPR), and oxygen storage capacity. XRD and Raman spectroscopy results showed that the use of ZrOCO3 or ZrO(NO3)(2) gave a CeO2-ZrO2 mixed oxide with a cubic phase of high thermal stability, while an extra C-phase was observed in the aged Pd/Ce0.45Zr0.45La0.1O1.95 catalyst prepared using Zr(NO3)(4). The activities of the three catalysts were evaluated using simulated exhaust gas under working conditions. The Pd/Ce0.45Zr0.45La0.1O1.95 catalyst prepared using ZrOCO3 as precursor gave the best activities for C3H8, CO, and NO conversion. The use of ZrOCO3 as precursor was better suited for the formation of Ce3+ and more favorable for the homogeneous insertion of Zr4+ and La3+ into the CeO2 lattice, which resulted in better thermal stability and enhanced redox properties of the Pd/Ce0.45Zr0.45La0.1O1.95 catalyst.

  Oxygen-storage materials CeO2-ZrO2-Al2O3 (CZA), with alumina contents 10, 25, 50, 75 and 90wt%, respectively, were prepared by the co-precipitation method. To compare our results with those of CeO2-ZrO2 (CZ), the prepared materials were characterized by Brunauer-Emmet Teller method (BET), X-ray diffraction (XRD), Raman spectrum, temperature-programmed reduction (H-2-TPR) and oxygen pulsing technique (OSC). The XRD and Raman results show that all samples (except sample with 90 wt% alumina) can keep the single CeO2 cubic fluorite structure after calcination at 873 and 1273 K for 5 h, respectively. Compared with the fresh samples, the particle sizes of aged samples increase, but no phase separation occurs. According to the results of BET and OSC, after calcination at 1273 K, alumina doped can make this system materials maintain higher specific surface area (114.5 m(2) g (- 1)) and larger pore volume (0.36 ml g (- 1)) without losing characteristics of CeO2. As Al2O3 contents increase, the ratio of utilizable cerium also increases, indicating that the OSC of CZA is more stable than that of CZ. In this work, the prepared CZA materials are highly dispersed composite solid solutions. After calcination at 1273 K, those compounds can still keep the structural and textural stability, and simultaneously hold excellent OSC and stable redox property. (c) 2007 Elsevier B.V.
