FIELD: internal combustion engines.
SUBSTANCE: disclosed is a catalytic product for use in processing exhaust of an internal combustion engine (embodiments), where one of embodiments comprises a substrate having a catalytic coating on it, wherein the catalyst coating comprises a catalyst layer, wherein the catalyst layer comprises a noble metal component on carrier particles, and where carrier particles have a bimodal particle size distribution comprising micrometre scale particles and nanoscale particles, where particles of micron scale have average size of particles ≥ 1 micron, and the nanoscale particles have an average particle size of ≤ 950 nm, the noble metal is palladium or platinum, and the catalyst layer contains cerium oxide, aluminium oxide and zirconium oxide. Also disclosed is exhaust gas processing system and method of exhaust gas processing of internal combustion engine, which contain catalytic product one of embodiments, which is described above. Besides, proposed is method of producing catalytic product one of embodiments described above.
EFFECT: technical result is meeting the need for more efficient catalysts for processing exhaust gases of an internal combustion engine.
