ВЛИЯНИЕ УСЛОВИЙ РЕГИДРАТАЦИИ НА СТРУКТУРНО-ПОВЕРХНОСТНЫЕ СВОЙСТВА ВОССТАНОВЛЕННЫХ СЛОИСТЫХ ДВОЙНЫХ ГИДРОКСИДОВ МАГНИЯ И АЛЮМИНИЯ

Abstract

The results of studies to determine the effect of rehydration conditions on the structural and surface properties of reduced layered double hydroxides of magnesium and aluminum are presented. It is shown that the samples obtained by the reduction of the heat-treated initial Mg-Al LDH for 2 hours (regardless of the medium used) have specific surface area indicators (both total and external) that do not differ from the original LDH sample, and their specific pore volume increases by 1.3–1.5 times (from 0.121 to 0.159–0.183 cm3/g).
