Electrochemical synthesis of CeO2 and CeO2/montmorillonite nanocomposites.
Nanocrystalline cerium oxide thin films on metal and semiconductor substrates have been fabricated with a novel electrodeposition approach - anodic oxidation. X-ray diffraction analysis indicated that as-produced cerium oxide films are characteristic face-centered cubic fluorite structure with 5 ~ 20 nm crystal sizes.openaire +1 more source
Role of CeO2 in Ni/CeO2–Al2O3 catalysts for carbon dioxide reforming of methane
Applied Catalysis B: Environmental, 1998Ni catalysts supported on gamma-Al2O3, CeO2 and CeO2-A1(2)O(3) systems were tested for catalytic CO2 reforming of methane into synthesis gas. Ni/CeO2-Al2O3 catalysts showed much better catalytic performance than either CeO2- or gamma-Al2O3-supported Ni catalysts.

Influence of CeO2 morphology on the catalytic activity of CeO2–Pt hybrids for CO oxidation
Dalton Transactions, 2013Ceria, because of its excellent redox behavior and oxygen storage capacity, is used as a catalyst for several technologically important reactions. In the present study, different morphologies of nano-CeO2 (rods, cubes, octahedra) were synthesized using the hydrothermal route.

Adsorption Kietics of Ceo2 Powders and Al Foam Loaded Ceo2
2013Cerium oxide powder and Aluminum loaded cerium oxide were prepared by hydrothermal method using cerium nitrate hexahydrate and urea as raw materials. Cerium oxide precursors and cerium oxide particles were characterized by field emission scanning electron microscopy. Results showed that two kind of size and morphology particles were prepared.

Improving the catalytic activity of CeO2/H2O2 system by sulfation pretreatment of CeO2
Journal of Molecular Catalysis A: Chemical, 2014Abstract Organic pollutants can be effectively degraded by CeO 2 /H 2 O 2 system, the catalytic activity of which is restricted by over-complexation of H 2 O 2 with CeO 2 . In this study, nano ceria was pretreated simply in different ways. Degradation of AO7 was employed to evaluate the catalytic activity of the pretreated ceria samples in the ...
