Nanostructured materials obtained under conditions of hierarchical self-assembly and modified by derivative forms of fullerenes

► We obtained gas-sensitive nanocomposites. ► Our composites based on silicon dioxide-metal oxide systems. ► We obtained nanocomposites via self-assembly by sol-gel method. ► Modification of the nanocomposites structure leads to increasing of specific surface area. ► Modification of the structure of nanocomposites allows to increase their gas sensitivity.
