Abstract
Use of a ternary vanadate of formula (I): Fex MeIy MeIIz VO4 wherein 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 A method of catalytically oxidizing carbonaceous compounds from a combustion engine, comprising:
- contacting a catalyst comprising a ternary vanadate of formula (I) with carbonaceous compounds from the combustion engine:
- Fex MeIy MeIIz VO4 (I),
- wherein 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,
- the catalyst catalysing oxidation of the carbonaceous compounds from the combustion engine.
A method of catalytically oxidizing exhaust gas from a combustion engine, comprising:
- contacting a catalyst comprising a ternary vanadate of formula (I) with exhaust gas from the combustion engine:
- Fex MeIy MeIIz VO4 (I),
- wherein 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
