Abstract
Novel oxidation-reduction catalysts and the method for their preparation. The materials comprise stable phases involving V.sub.2 O.sub.3 and TiO.sub.2 and mixtures of said phases and have compositions that fall within specific areas in a binary composition diagram of V.sub.2 O.sub.3 and TiO.sub.2. A typical VT material has the formula V.sub.2 TiO.sub.5. A typical E material has a formula V.sub.2 Ti.sub.2 O.sub.7 ; and, a typical .eta. material has the formula V.sub.2 Ti.sub.3 O.sub.9.
