Bibliographic description in the original language

Structural and textural properties of pillared montmorillonite at intercalation of large Al- and Al/Ce-polyhydroxocomplexes

Annotation

The possibility of adjusting the separation of silicate layers in montmorillonite in a broad range of basal distances d001 (1.3–2.4 nm) at the intercalation of large (0.7–1.8 nm) polyhydroxocomplexes of aluminum ([Al13O4(OH)24(H2O)12]7+, [Al30O8(OH)56(H2O)24]18+) and aluminum/cerium synthesized through the combined hydrolysis of aluminum and cerium salts in a reactor under pressure is shown. The formation of polyhydroxocomplexes was controlled by the methods of 27Al NMR and photon correlation and fluorescent spectroscopy at different concentrations of Al3+ ions (2.5–5.1 M) in solution. Textural properties (specific surface area, total pore volume, and mesoporosity) and fractal dimensionality of the samples of intercalated montmorillonite obtained by annealing at 300?C have been determined using the method of low-temperature nitrogen adsorption–desorption. ? 2015, Pleiades Publishing, Ltd.
