Synthesis and Characterization of Cerium Oxide (CeO₂) Nanoparticles

Abstract:

Nanoparticles of cerium oxide (CeO2) are synthesized with cerium (III) nitrates (Ce(NO3)3, 6H2O) by precipitation method in ammonium hydroxyl solution (NH4OH). The influence of several parameters such as nature of the solvent, synthesizing temperature and the calcination on the crystallite size is studied by XRD, TEM and BET methods. The results show that both calcinations and synthesizing temperature affect the particles size. Also, the nature of solvent has a great effect on the morphology of CeO2 nanoparticles.

Room Temperature Growth of Cerium-Iron Oxide Nanorods

Authors: N. Sabari Arul, D. Mangalaraj, N. Ponpandian, Pao Chi Chen, Junsin Yi

Abstract: Cerium-iron oxide composite nanorods were synthesized by a surfactant free precipitation method. The synthesized products were characterized by XRD, FESEM, BET and TEM. Increase in the mole concentration causes the morphology of the cerium oxide to change from nanorods into nanocubes. X-ray diffraction pattern shows a diffraction peak at 28.5° corresponding to (111) reflection plane normal to c axis of a cubic fluorite structure of CeO2 and also hexagonal phase of Fe2O3 and orthorhombic phase of FeO (OH). EDAX analysis on individual nanorod conform the presences of Iron, which supports the XRD spectra. From transmission electron microscopy (TEM), the length and width of the nanorods were estimated in the range of ~100-350 nm and ~20-40 nm respectively. The Brunauer Emmett Teller (BET) analysis showed the increase in surface area for the obtained nanorods with respect to the increase in Fe concentration which in turn enhanced the formation and growth of nanorods.

Synthesis and Characterization of CeO₂-ZrO₂-Al₂O₃ with High Thermal Stability and Oxygen Storage Capacity from Pseudoboehmite Precursor

Authors: Dong Zhang

Abstract: The surface and structural properties, thermal stability and oxygen storage capability are inverstigated in ceria-zirconia-alumina oxide with deposition coprecipitation method using the Pseudoboehmite precursor. X-ray diffraction (XRD), Brunauer-Emmet Teller method (BET), Transmission electron microscopy (TEM) and oxygen pulsing technique are used to character the prepared materials. The prepared ceria-zirconia-alumina oxides are highly dispersed composite solid solution. After calcination at 650 °C and 1000 °C respectively, these compounds can still keep the structural and textural stability and hold excellent oxygen storage capability.

The Combustion Synthesis of Nanoscale Ceria-Doped Calcia Solid Solution

Authors: Jing Xu, Qing Hua Chen, Xin Ping Liu, Bao Quan Huang, Qing Rong Qian

Abstract: A nanoscale ceria-doped calcia solid solution has been synthesized by controled self-combustion method. The difference in crystal structure of samples prepared from different fuels were identified by XRD. The change of the crystal structure of the ceria-doped calcia sintering at different temperature was also investigated. SEM indicates that a nanoscale and uniform particle with diameter less than 100 nm was achieved by this method.

Fabrication and Characterization of Barium Doped Ceria Nanopowders by a Solvothermal Processing

Authors: Dae Han Lee, Dong Sik Bae

Abstract: Ba doped CeO₂ nanopowders were prepared under mild temperature and pressure conditions by precipitation from metal nitrates with aqueous ammonium hydroxide. Spherical Ba doped CeO₂ nanopowders were obtained with reaction at the temperature range of 210°C to 230°C for 6 h. The average size of the synthesized Ba doped CeO₂powders were below 10 nm and its distribution was narrow. The XRD pattern showed that the synthesized Ba doped CeO₂powders were crystalline with cubic phase of CeO2. This study has shown that the synthesis of Ba doped CeO2 nanopowders is possible under mild temperature and pressure conditions in ethylene gylcol solution. The effects of synthesis parameters, such as the solvent ratio of starting solution, pH of starting solution, reaction temperature and time, are discussed.
