Abstract
Several synthesis routes have been developed and correlations between the variables of the synthesis procedure and the physicochemical properties of nanoporous silica materials of the MCM-48 type deposited by the template method in the presence of a low-valent iron (II) cation have been investigated. Changes in the structure of silica mesoporous framework, its textural properties and the degree of energy inhomogeneity of the surface were studied depending on the Fe/Si molar ratio, pH values (4 and 9 units), stepwise calcination (673 and 923 K) and extraction of cetylpyridinium template with ethanol from xerogels.
