To solve the problem of poor low-temperature NH3 selective catalytic oxidation (NH3–SCO) performance CeZrOx catalysts, a series Ru/CeZrOx catalysts with various Ru mass ratios were prepared via impregnation–precipitation method. The introduction could significantly improve from activity test results. Among catalyst ratio 0.5 wt % and Ce/Zr molar 7:3 (denoted as Ru0.5/CZO) was considered to have an excellent NH3–SCO performance; conversion reached 100 91.2% N2 selectivity at 237 °C. Physicochemical properties Ru0.5/CZO CZO compared through characterization tests investigate relationship between performance. H2-TPR results revealed interaction Ce species. shifted reduction peak toward lower-temperature direction, enhancing redox catalyst. NH3-TPD indicated that had abundant acid sites on its surface, facilitating adsorption oxidation. In situ DRIFTS reaction mechanism might be both internal-selective (i-SCR) imine (−NH) mechanisms.
