  Thermal decomposition of homo- and heterometallic (η6-arene)tricarbonylchromium derivatives

  摘要：

  The thermal decomposition of homo- and heterometallic (eta(6)-arene)tricarbonylchromium complexes in dry air has been investigated by thermogravimetric analysis. The final decomposition products are characterized by X-ray powder diffractometry which confirms the formation of Cr2O3, PdO and Co2CrO4 (C) 1999 Elsevier Science B.V. All rights reserved.

  Synthesis, characterization and application of nano-sized Co2CrO4 spinel catalyst for selective oxidation of sulfides to sulfoxides

  摘要：

  The nano-sized Co2CrO4 spinel was produced for the first time by thermal decomposition of Cr-Co gel prepared by sol-gel method. It was shown that well-crystallized spinel structure is formed after calcination at 450 degrees C. The usual characterizations were performed and the results showed the particle size of the prepared spinel is 9 nm. Moreover, the prepared nano-sized Co2CrO4 spinel was applied in a simple, efficient and recyclable method for selective oxidation of sulfides to their corresponding sulfoxides with aqueous hydrogen peroxide in tert-butanol.

  Thermolysis of the double-metal complex [Co(NH3)(6)][Cr(C2O4)(3)] was studied in air at 200, 350, and 500 degrees C and in a hydrogen atmosphere at 200, 350, 500, 700, and 900 C, as well as the composition and properties of thermolysis products. Oxidative thermolysis produces mixed oxides CoCr2O4 and Co2CrO4; reductive thermolysis produces Co+Cr2O3 mixture. Specific surface areas were measured for reductive thermolysis products; the maximal specific surface area and, therefore, maximal dispersion are reached at 500 degrees C. The morphology of the reductive thermolysis products and the thermolysis chemism were studied in relation to the nature of the complex anion.
