摘要:
We have done comparative XAFS analysis on the Mo K and W L(3) edges of polycrystalline MO(x)W(1-x)O(3) solid solutions. It was found that their structures are closely related to corner-shared WO3-type for x < 0.9 while alpha-MoO3-type structure is present for x greater than or equal to 0.9. The obtained structural parameters for the first shell around metal ions allow to distinguish several structural phase transitions due to the change of composition. A set of subshells within the first shell was found, and they are in good agreement with Raman data.
