摘要：

XAS provides clear evidences that the tetravalent cations are not incorporated within Layered Double Hydroxide (LDH) sheets. The cations are segregated, presenting a local order close to that of SnO2 rutile. However, the nature of the LDH influences slightly the local order probably due to some surface effect microtexture. Variation of the cell parameters for the LDH materials are explained by a substitution of Al cations by divalent cations M(II).
