Comparative Structural and Spectroscopic Characterization of MI LnIIITiO4 Ion-exchanged Phases, with MI : Na, H, K
In this paper, a comparative study of the XRD characterization and FTIR spectroscopic behavior of some MILnIIITiO4 phases with MI : Na, H, K and LnIII, the trivalent lanthanides elements: Sm, Eu, Er and Yb is reported. The H and K- oxides were obtained by ion-exchange from NaLnTiO4 . These ternary o...

| Sumario: | In this paper, a comparative study of the XRD characterization and FTIR spectroscopic behavior of some MILnIIITiO4 phases with MI : Na, H, K and LnIII, the trivalent lanthanides elements: Sm, Eu, Er and Yb is reported. The H and K- oxides were obtained by ion-exchange from NaLnTiO4 . These ternary oxides belong to the K2NiF4 structural type, with the MI and LnIII cations distributed in an ordered way on the K-sub lattice. The FTIR spectra of the materials were analyzed by comparison with structurally related materials. A close relationship with the parent NaLnTiO4 was found. |
