Abstract

Nanostructured film materials and powders of xerogels have been obtained from sols on the basis of MeOx-SiO2 (Me = Fe, Co, Ni, Er) systems and the four-component Fe2O3-NiO-Co3O4-SiO2 system using the sol-gel method. Nanocomposite materials have been studied by atomic-force microscopy, X-ray phase analysis methods, and the four-point Brunauer-Emmett-Teller method on thermal desorption of nitrogen. The conditions of the formation of the crystalline phases of metal oxides have been determined and the possibility of obtaining nanostructured materials under conditions of self-assembling with the developed surface has been demonstrated.
