The Non-Sodium Nickel Hydroxycarbonate for Nanosized Catalysts

The samples of non-sodium nickel hydroxycarbonate for nanosized catalysts have been obtained and investigated. The ratio of crystalline water, the amount of nickel hydroxide and carbonate has been calculated. By the X-ray analysis of obtained nickel oxide the crystallite size of 12–13 nm has been determined. The samples of catalysts provided a high specific surface.

Regularities of Obtaining, Morphology and Properties of Metal-Containing Polymer-Silicate Materials and Polyester Composites on their Basis

The effect of the kind, concentration and introduction method of polymeric modifiers (polyvinyl alcohol and polyvinylpyrrolidone), as well as the kind of metal chloride on the physico-chemical regularities of the obtaining process of modified metal-containing polymer-silicate materials, their morphology and properties has been examined. Using instrumental methods of investigations it was established that obtaining of metal-containing polymer-silicate materials was accompanied by intermolecular interactions between active silicate groups and functional groups of a polymeric modifier.
