Use of a ternary vanadate of formula (I): FeMeIMeIIVOwherein MeI and MeII are different from each other and each stand for an element selected from the group consisting of Y, La, Ce, Pr, Nd, Sm, Er, Gd, Tb, Dy, Ho, Tm, Yb, Lu, Al, Bi and Sb and wherein x=0.05-0.9; y=0.05-0.9; z=0.05-0.9; x+y+z=1, as a catalyst for the oxidation of carbonaceous compounds in combustion engines.

Use of vanadates as oxidation catalysts

A catalyst composition comprising a vanadate represented by the formula XVO/S, wherein XVOstands for a Bi-, Sb-, Ga- and/or Al-vanadate optionally in mixture with one or more rare earth metal-vanadates, or in mixture with one or more transition metal-vanadates, or in mixture with one or more transition metal-vanadates and one or more rare earth metal-vanadates, and S is a support comprising TiO, optionally in combination with a dopant and a process for the preparation of such catalyst compositions.

Catalyst composition for selective catalytic reduction of exhaust gases

Catalyst composition represented by the general formula REVO/S wherein RE is at least one of the group of rare earth metals Y, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Er and Yb in an amount of up to 6.0 wt.-%; V is vanadium in an amount of 0.2-2.5 wt.-%; O is oxygen in an amount of up to 3.5 wt.-%; and S is a support containing TiOin an amount of at least 70 wt.-%, with the rest being WOand optionally SiO. This catalyst composition shows high removal efficiencies for NOeven after aging at 750&#xb0; C.

Exhaust gas catalyst composition

A catalyst composition represented by the general formula XVO/S wherein XVOstands for TransitionMetal-Vanadate, or a mixed TransitionMetal-/RareEarth-Vanadate, and S is a support comprising TiO.
