    RuO 2 · x H 2 O胶体的表征及其介导水氧化的能力
    摘要:
    制备了由聚乙烯负载的RuO 2 · x H 2 O胶体,表征并评价为O 2催化剂。从胶体中析出的RuO 2 · x H 2 O的热分析(tga和dtga)表明存在弱结合和紧密结合的水。动态光散射表明,凝结的胶体颗粒较大(d = 825 nm)且带正电。透射电子显微镜表明,胶体颗粒本身是微晶的聚集体,太小(<10 nm)而无法清晰分辨。在高电解质浓度的条件下,胶体被证明对凝结不稳定(10 –3 mol dm –3),即使电解质是H 2 SO 4。在存在Ce IV离子的情况下,胶体确实表现出了作为O 2催化剂的某些活性(O 2产率= 73%),但也对RuO 4进行了阳极腐蚀(27%)。在低浓度的Ce IV离子(4.5×10 5 mol dm –3)和胶体([RuO 2 ] = 0.02–0.00125 g dm –3)的情况下,胶体似乎通过Ce IV介导了比水对氧化的氧化离子。在这些条件下以及在高恒定背景浓度的聚苯(0

    Two Ce(SO4)2·4H2O polymorphs: Crystal structure and thermal behavior
    摘要:
    Syntheses, crystal structures and thermal behavior of two polymorphic forms of Ce(SO4)(2)center dot 4H(2)O are reported. The first modification, alpha-Ce(SO4)(2)center dot 4H(2)O (1), crystallizes in the orthorhombic space group Fddd, with a = 5.6587(1), b = 12.0469(2), c = 26.7201(3) angstrom and Z = 8. The second modification, beta-Ce(SO4)(2)center dot 4H(2)O (II), crystallizes in the orthorhombic space group Pnma, with a = 14.6019(2), b = 11.0546(2), c = 5.6340(1) angstrom and Z = 4. In both structures, the cerium atoms have eight ligands: four water molecules and four sulfate groups. The mutual position of the ligands differs in (1) and (11), resulting in geometrical isomerism. Both these structures are built up by layers of Ce(H2O)(4)(SO4)(2) held together by a hydrogen bonding network. The dehydration of Ce(SO4)(2)center dot 4H(2)O is a two step (1) and one step (II) process, respectively, forming Ce(SO4)(2) in both cases. During the decomposition of the anhydrous form, Ce(SO4)(2), into the final product CeO2, intermediate XCeO2 center dot YCe(SO4)(2) species are formed. (c) 2007 Elsevier Inc. All rights reserved.

    Copper-Mediated Intramolecular N–N Bond Coupling Using Cerium(IV)­ Sulfate as the Oxidant for the Synthesis of 5-Thio-Substituted­ 1,2,4-Triazoles
    摘要:
    A method for copper(II)-mediated N-N bond formation of N-imidoylisothioureas has been developed for the synthesis of 1,2,4-triazoles. The reaction requires cerium(IV) sulfate as an oxidant and proceeds at room temperature. This approach provides access to a variety of substituted 1,2,4-triazoles.
