FIELD: chemistry.
SUBSTANCE: claimed invention relates to catalysts for processes of selective catalytic reduction of NOx compounds in exhaust fumes and output gases from burning processes. According to invention catalysts include catalytically active metal component and particles of mixed TiO2/ZrO2 porous carrier, which contain: a) crystal phase, which contains titanium dioxide and/or titanium/zircon mixed dioxide, b) zircon-containing amorphous phase, and c) small quantity of one or several oxides of metal (metals) or oxides of metalloid (metalloids), precipitated on external amorphous layer. Described are porous carrier of catalyst and method of its obtaining, method of catalyst obtaining and method of reduction of compounds NOx in gas or liquid phase with application of upper described catalyst.
EFFECT: improved parameters of transformation degree, selectivity, as well as reduction of by-product (nitrous oxide) formation especially at increased temperature.
