FIELD: chemistry.
SUBSTANCE: composition is based on zirconium oxide, silicon oxide and one oxide of another element M, selected from titanium, aluminium, tungsten, molybdenum, cerium, iron, tin, zinc and manganese, with the following weight ratio of these different elements: silicon oxide: 5-30%; oxide of element M: 1-20%, and up to 100% zirconium oxide, wherein the composition has acidity defined in experiments using methylbutanol equal to at least 90%. Said composition can be obtained using a method in which a liquid medium is mixed with a zirconium compound, a silicon compound, a compound of element M and a basic compound, as a result of which a precipitate forms; the precipitate then matures in the liquid medium, separated and then calcined.
EFFECT: composition is effective in treating exhaust gases of diesel engines.
