Lattice Constant Dependence on Particle Size for Bulk and Doped Ceria prepared from a Citrate Sol-Gel
High surface area ceria nanoparticles have been prepared using a citrate sol-gel precipitation method. Changes to the particle size have been made by doping ceria powders, and calcining at different temperatures. Xray methods were used to determine their lattice parameters. The particle sizes have been assessed using transmission electron microscopy (TEM) and the lattice parameter found to fall...
متن کاملHigh Surface Area Ceria for CO Oxidation Prepared from Cerium t-Butoxide by Combined Sol–Gel and Solvothermal Processing
ABSTRACT CeO2 was synthesized by combined sol-gel and solvothermal processing of gels obtained from acetaldoximate-modified cerium(IV) t-butoxide in the presence of the non-ionic surfactant Pluronic F127. The use of cerium(IV) t-butoxide as precursor contrasts very favorably with the often used ceric ammonium nitrate and results in more reliable and tailorable properties of the final materials....
متن کاملHybrid polysaccharide-silica nanocomposites prepared by the sol-gel technique.
New monolithic nanocomposite silica biomaterials were synthesized on the basis of various natural polysaccharides and recently introduced completely water-soluble precursor tetrakis(2-hydroxyethyl) orthosilicate. The sol-gel processes were performed in aqueous solutions without the addition of organic solvents and catalysts. The silica polymerization was promoted by the polysaccharides through ...
متن کاملSol-Gel-Prepared Nanoparticles of Mixed Praseodymium Cobaltites-Ferrites
Two series of nanocrystalline powders of PrCo1 - x Fe x O3 (x = 0.1, 0.3, 0.5, 0.7 and 0.9) of high purity were obtained by sol-gel citrate method at 700 and 800 °C. The formation of continuous solid solution with an orthorhombic perovskite structure (sp. group Pbnm) was observed. A peculiarity of the PrCo1 - x Fe x O3 solid solution is the lattice parameter crossovers, which occurred at certai...
متن کاملZnO films prepared by modified sol-gel technique
Zinc oxide films with different thicknesses have been synthesized by modified sol-gel technique. The films are polycrystalline in nature with average grain size between 32 and 57 nm. The thicker films are less strained than the thinner ones. The optical band gap of the films is ~ 3.22 eV. PL spectra are dominated by a strong luminescence peak at ~387 nm followed by a low intensity peak ~469 nm....
