Development of a combined formation method of ZnO/TiO$_2$ nanotube

The conditions for the formation of nanostructured materials based on ZnO nanorods and TiO$_2$ nanotubes formed on their basis, the optimal modes of application and the required thickness of the seeding ZnO layers have been determined. The time and temperature regimes for hydrothermal synthesis of columnar nanostructures based on zinc oxide were selected experimentally. The method of atomic force microscopy was used to study the morphology and sub-roughness of the surface. Using a scanning electron microscope, a detailed study of the structure and morphology of the obtained nanostructured materials was carried out at each stage of synthesis. The main characteristics influencing the size and shape of the obtained ZnO/TiO$_2$ nanostructured materials have been established.
