Abstract
The present project work deals with the synthesis and characterization of doped porous
nanopowders, which has high thermal resistance, improved reduction efficiency of the
redox couple, excellent oxygen storage/release capacity and better catalytic activity at lower temperature than pure ceria.
oxides with different
content (0, 2, 5,10 mol %) were prepared. The work involves a systematic study and analysis of the structures of the samples prepared under different conditions. Mesoporous
nanopowders synthesized in cubic fluorite structure, which is stable up to as high as
using an inorganic salt of zirconium and surfactants of dodecyl amine and sodium dodecyl sulphate. FTIR results show that the mesoporous
nanopowders heated at
is free from surfactant. The results of the porous
formation and their stabilities, phase transformation, crystallite sizes and microstructures are studied with X-ray diffraction, IR analysis, and SEM analysis. The XRD data’s showed the as prepared
powder particles have single phase cubic fluorite structure.
