FIELD: environmental protection.
SUBSTANCE: catalyst includes metal oxide substrate consisting mainly of cerium and/or zirconium oxide. Noble metal and metal or semimetal oxide (MOx) are attached to metal oxide substrate, where M is selected out of group including iron, gallium, silver, molybdenum, tungsten, thallium and bismuth. Metal or semimetal M has larger electronegativity than that of cerium or zirconium.
EFFECT: enhanced activity of noble metal in catalyst at low temperatures, prevented caking of noble metal.
