Stable solid phases involving V2O3 - TiO2 and mixtures of said phases

摘要

Novel oxidation-reduction catalysts and the method for their preparation. The materials comprise stable phases involving V2O3 and TiO2 and mixtures of said phases and have compositions that fall within specific areas in a binary composition diagram of V2O3 and TiO2. A typical VT material has the formula V2TiO5. A typical E material has a formula V2Ti2O7; and, a typical eta material has the formula V2Ti3O9.
