Реферат:
The reductive decomposition of the complex Pd2Eu2(μ,η2‐OOCMe)2(μ‐OOCMe)8(H2O)2·(HOOCMe)2 upon heating from room temperature to 500 °C in a hydrogen atmosphere was investigated by in situ synchrotron radiation‐based X‐ray absorption fine structure spectroscopy (XAFS) including observations of X‐ray near‐edge structure (XANES) and extended absorption fine structure (EXAFS) at Pd K‐ and Eu L3‐edges and synchrotron X‐ray diffraction (XRD). The Pd‐Eu2O3 nanocomposite was found to be the final thermolysis product. The decomposition proceeds via series of intermediate crystalline phases, including europium(II) and (III) anhydrous acetates and EuO(CH3COO) oxidoacetate. Surprisingly, the major fraction of europium occurs in the reduced form Eu2+ within a limited temperature range of 200–300 °C. Presumably, the reversible Eu3+↔Eu2+ redox‐process is associated with the stability of nanocrystalline palladium hydride, which acts as a stronger reducing agent as compared to molecular hydrogen.
