Abstract
Cryptomelane type manganese oxides were prepared by the
redox precipitation method. Modified materials were obtained by the direct
introduction of silver to the synthesis mixture or by impregnation of the
obtained oxides. The structure of the oxides was investigated by the FT-IR
and FT-IR/PAS methods. It was found that the presence of silver in the
synthesis conditions of manganese oxides caused partial replacement of
potassium from the channels and distortion of the cryptomelane structure. In
the impregnating samples silver was located on the outer surface of the
oxides grains. FT-IR and FT-IR/PAS studies revealed different nature of bulk
and surface interactions in the samples.
