It was found that an increase in manganese content to 3.6% wt. (molar ratio Mn/(Zr + Ce) ≤ 0.1) leads to an increase in the catalytic activity of MnО<italic><sub>x</sub></italic>/Zr<sub>0.4</sub>Ce<sub>0.6</sub> in oxidation reactions. In the case of a higher manganese concentration, the activity changes slightly. According to the XRD, TPR-H<sub>2</sub>, XPS and EPR, an increase in the amount of supported manganese for samples with Mn/(Zr + Ce) ≤ 0.1 is accompanied by a change in the lattice constant of the support, an increase in the amount of weakly bound oxygen, as well as the quantity of oxygen vacancies in the structure of cerium oxide. These changes are due to the incorporation of manganese into the structure of the support and the possible formation of highly dispersed particles of MnО<italic><sub>x</sub></italic> on its surface which ensures an increase in catalytic activity. Stabilization of catalytic activity with a further increase in the amount of supported manganese correlates with a slight change in the amount of weakly bound oxygen and oxygen vacancies of the support due to the appearance and subsequent increase in the content of the less active Mn<sub>2</sub>O<sub>3</sub> phase.</p></abstract><trans-abstract xml:lang="ru"><p>Изучено влияние содержания нанесенного марганца на структурные свойства и активность в реакциях окисления СО и пропана для катализаторов MnО<italic><sub>x</sub></italic>/Zr<sub>0.4</sub>Ce<sub>0.6</sub>, приготовленных методом пропитки. Установлено, что по мере повышения содержания марганца до 3.6 мас.% (мольное отношение Mn/(Zr + Ce) ≤ 0.1) каталитическая активность MnО<italic><sub>x</sub></italic>/Zr<sub>0.4</sub>Ce<sub>0.6</sub> в реакциях окисления растет, при нанесении бόльшего количества марганца — меняется слабо. Согласно данным рентгенофазового анализа (РФА), термопрограммированного восстановления водородом (ТПВ-Н<sub>2</sub>), электронного парамагнитного резонанса (ЭПР) и рентгеновской фотоэлектронной спектроскопии (РФЭС) для образцов состава Mn/(Zr + Ce) ≤ 0.1 увеличение количества нанесенного марганца сопровождается изменением параметра решеток фаз носителя, возрастанием количества слабосвязанного кислорода, а также количества кислородных вакансий в структуре оксида церия, ростом поверхностной концентрации марганца. Эти изменения обусловлены вхождением марганца в структуру носителя и возможным образованием высокодисперсных частиц MnО<italic><sub>x</sub></italic> на его поверхности, что объясняет наблюдаемое повышение каталитической активности. Стабилизация каталитической активности при дальнейшем увеличении количества нанесенного марганца коррелирует со слабым изменением количества слабосвязанного кислорода и кислородных вакансий носителя в связи с появлением и последующим ростом содержания менее каталитически активной фазы Mn<sub>2</sub>O<sub>3</sub>.</p></trans-abstract><kwd-group xml:lang="en"><kwd>MnOx/ZrO2-CeO2 catalysts</kwd><kwd>CO oxidation</kwd><kwd>propane oxidation</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>катализаторы MnOx/ZrO2–CeO2</kwd><kwd>окисление СО</kwd><kwd>окисление пропана</kwd></kwd-group><funding-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Российский научный фонд</institution></institution-wrap><institution-wrap><institution xml:lang="en">Russian Science Foundation</institution></institution-wrap></funding-source><award-id>21-73-10218</award-id></award-group><award-group><funding-source><institution-wrap><institution xml:lang="ru">Министерство науки и высшего образования Российской Федерации</institution></institution-wrap><institution-wrap><institution xml:lang="en">Ministry of Science and Higher Education of the Russian Federation</institution></institution-wrap></funding-source><award-id>FWUR-2024-0032</award-id></award-group></funding-group></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Everaert K., Baeyens J. // J.
