Abstract:	The influence of synthesis conditions and Mg²⁺, Co²⁺, and Zn²⁺ admixtures on the formation of lamellar, cubic, and hexagonal mesophases was studied. After calcining at 653 K in an argon flow, the mesophases transformed into mesoporous materials with D _pore = 27–80 Å, V _pore = 0.10–0.30 cm³/g, and s _BET = 80–200 m²g. Nanotubes based on mesostructural lamellar vanadium oxide with inside diameters of from 100 to 500 Å were obtained in the presence of several amines as templates.
