Preparation and Characterization of Mesoporus Nanopowders Using Dodecylamine and Sodium Dodecyl Sulfate as Surfactant

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.
