FIELD: instrument engineering.
SUBSTANCE: invention relates to a hydrolysis catalyst for the reduction of nitrogen oxides made in the form of a catalytic coating. As a compound adsorbing HNCO and nitrogen oxides, the said hydrolysis catalyst comprises lanthanum and further comprises one of the following: an alkaline earth metal, yttrium, praseodymium, gallium, zirconium, herewith the catalytic coating from the said hydrolysis catalyst is a coating based on titanium dioxide, based on SiO2, based on a zeolite, and/or based on zirconium dioxide. Invention also relates to a catalytic structure including the hydrolysis catalyst, as well as to its use.
EFFECT: technical result is to increase the efficiency of the hydrolysis catalyst.
