Book Synopsis Preparation and Characterization of Co(II)/ZrO2 Solid Solution by : Ping Wu
Download or read book Preparation and Characterization of Co(II)/ZrO2 Solid Solution written by Ping Wu and published by . This book was released on 1987 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Samples of cubic zirconium oxide containing up to almost 10 atomic percent cobalt were prepared by codecomposition of the nitrate. Magnetic susceptibility measurements confirmed the limit of solubility and the presence of the cobalt as Co(II). The reduction of the cobalt inserted in cubic zirconia took place at a considerably higher temperature than bulk cobalt oxide. Cubic Zro2 samples containing some transition metal oxides including rhodium oxide (1), iron oxide (2), chromium oxide (3) and nickel oxide (4) were studied previously in this laboratory. Their structures, magnetic properties and the stabilities towards reduction have been studied. Zro2 is characteristic of an absence of reaction between the ZrO2 support and the catalyst. It is the purpose of this work to investigate the formation of solid solution between ZrO2 and cobalt oxide and to study the magnetic properties of such a system. In addition, the stability towards reduction of cubic Zro2 samples containing various concentrations of reacted cobalt oxide will be determined.

Book Synopsis Preparation and Characterization of Cubic ZrO2 Stabilized by Fe(III) and Fe(II). by : S. Davison
Download or read book Preparation and Characterization of Cubic ZrO2 Stabilized by Fe(III) and Fe(II). written by S. Davison and published by . This book was released on 1987 with total page 17 pages. Available in PDF, EPUB and Kindle. Book excerpt: Samples of cubic zirconium oxide contained 2.5at% - 40af% ferric iron were prepared by codecomposition of the nitrates. X-ray powder diffraction analysis and magnetic measurements indicated that alpha iron nitrate and ZRO2 form a solid solution up to 25at% Fe/Zr in the product. At this point, the solubility limit of alpha-Fe2O3 in ZrO2 is exceeded. The reduction of cubic zirconia samples containing 2.5at% - 20at% Fe(III) leads to the stabilization of iron (II) in the zirconia lattice. Reduction to metallic iron occurs at much higher temperatures than the reduction of bulk alpha-Fe2O3. (Reprints).

Book Synopsis Preparation and Characterization of ZrO2 Stabilized with Ru(IV) and La(III). by : Y-C. Long
Download or read book Preparation and Characterization of ZrO2 Stabilized with Ru(IV) and La(III). written by Y-C. Long and published by . This book was released on 1988 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ruthenium oxide, dispersed on oxide supports such as TiO2, SiO2, and ZrO2, are known to shown Fischer-Tropsch activity. Little is known about the catalyst-support interactions which must play an important role in the catalytic activity of dispersed ruthenium oxide. The strength of catalytic support interaction may be directly related to the stability of the dispersed catalyst towards reduction. Hence, solid solutions of Ru(IV)/ZrO2 have been prepared, and the resulting stability of Ru(IV) toward reduction with hydrogen was measured and compared with that of bulk RuO2. The observed increase in stability toward reduction was related to interaction between RuO2 and ZrO2. The introduction of a small amount of La2O3 with the ZrO2 produced further stabilization of the Ru(IV) toward reduction.

This book was released on 1988 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cu(II) is known to prefer square planar or tetrahedral coordination in many oxides. The introduction of Cu(II) in the rock salt or fluorite structures would represent unusual structural behavior and be of interest in catalysis where new oxide supports are being investigated. The systems CuO/MgO and CuO/ZrO2 were studied and the nature of the products were characterized by x ray diffraction analysis, temperature programmed reduction studies and magnetic susceptibility. Although some stabilizations occurs for Cu(II) in ZrO2, a much greater stabilization was observed in the rock salt structure CuXMg1-x0. Copper oxides, Magnesium oxides, Zirconium oxides. (mjm).
