Impact of aqueous impregnation on the long-range ordering and mesoporous structure of cobalt containing MCM-41 and SBA-15 materials

Analysis of XRD intensities suggested that after aqueous impregnation and drying a considerable amount of cobalt ions was located in the SBA-15 mesopores. Nitrogen adsorption-desorption data indicated plugging a part of SBA-15 mesopores in cobalt containing samples. Due to the high stability, SBA-15 silica appears to have a good potential for its use as a support for metal and oxide catalysts.
