Vanadyl pyrophosphate catalyst

Centi, G., Ed., Vanadyl Pyrophosphate Catalysts, Catal. Today 16 (1993). 

Related work includes investigations of carbon formation during hydrogenation of C5 hydrocarbons catalyzed by nickel and palladium (5P) interactions of N2O with a hydrotalcite-derived multimetallic mixed oxide catalysts (60,61) changes in mass of solid oxides (62) methanol sorption in Nafion-117 (proton-exchange) membranes (63) vanadyl pyrophosphate catalysts for butane oxidation (64-66) and deactivation/regeneration of a Rb0 c/Si02 catalyst for methylene valerolactone synthesis (67). 

In both aqueous and organic syntheses, the VOHPO4 0.5H2O precursor has a P/V ratio higher than the stoichiometric value [10,16,19]. The maximum value corresponds to P/V = 1.1, while the excess phosphate remains in synthesis solution. The X-ray photoelectron (XPS) analysis indicates that the excess phosphate is localized at the surface of the vanadyl pyrophosphate catalysts (surface P/V = 1.5-3.0) [23].
