摘要：
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.
