MESOSTRUCTURED VANADIUM-OXIDE CONTAINING DODECYLAMINE

Two lamellar (L1, L2) and one hexagonal (H) vanadium oxide-dodecylamin e mesophases have been prepared and characterized by XRD, FTIR, SEM, T EM, and NMR spectroscopy. The local environment of vanadium species wa s found to be controlled mainly by the synthesis temperature regardles s of the nature of the mesophase. It was proposed that the structure o f the final phase is governed by the acidity of the vanadium centers, and thus by the strength of the interactions between these centers and dodecylamine.
