The present invention relates to the use of a composition of formula (I): FeNiCoMSSe, wherein M stands for one or more elements having in the ionic state an effective ionic radius in the range of 70-92 pm, a is a number within the range of 2.5≤a≤3.5, more preferably 2.7≤a≤3.3, b is a number within the range of 1.5≤b≤5.0, more preferably 1.5≤b≤4.0, most preferably 2.5≤b≤3.5, c is a number within the range of 0.0≤c≤2.0, more preferably 0.0≤c≤1.0, d is a number within the range of 0.0≤d≤4.0, more preferably 0.0≤d≤1.0, wherein the sum of a, b and c is in the range of 5≤a+b+c≤8 and wherein ≥90 wt. % of the composition is in the pentlandite phase for electrocatalytic splitting of water, preferably for hydrogen evolution reaction.

Use of sulfidic compositions

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 composition of formulaCeNMDO&#x2003;&#x2003;Iwherein M stands for one or more elements from the group of alkaline metals, except sodium, N is Bi and/or Sb, D is present, or is not present, and if present is selected from one or more of Mg, Ca, Sr, Ba; Y, La, Pr, Nd, Sm, Gd, Er; Fe, Zr, Nb, Al; a is a number within the range of 0&#x3c;a&#x2264;0.9, b is a number within the range of 0&#x3c;b&#x2264;0.3, c is a number within the range of 0&#x3c;c&#x2264;0.2, a plus b plus c is &#x3c;1, and x is a number within the range of 1.2&#x2264;x&#x2264;2, and its use for exhaust gas aftertreatment systems of Diesel engines, gasoline combustion engines, lean burn engines and power plants.
