    XPS and FTIR characterization of manganese ions deposited on alumina
    (Elsevier, 1999-05-25) Kantcheva, M.; Kucukkal, M. U.; Süzer, Şefik
    By application of XPS and FTIR spectroscopy of adsorbed CO the effect of preparation conditions on the state and localization of manganese ions deposited on h-Al2O3 is studied. Both Mn21 and Mn31 ions are observed on the impregnated sample. The sample obtained by ion exchange contains only Mn31 ions. The adsorbed CO species are identified. q 1999 Elsevier Science B.V.
