Аннотация
Correlations between the preparation conditions and the physicochemical properties of MCM-48 nanoporous silica deposited by the template method in the presence of ferro-ion have been studied. The change in the structure of the mesoporous silica skeleton, its textural properties, and energy inhomogeneity of the surface, depending on the Fe/Si molar ratio, pH value, calcination temperature, and xerogel detemplating by solvent extraction, was studied.
