| Summary: | Metal–organic frameworks (MOFs) are demonstrated to exhibit high catalytic activity for their unique porous structure and dispersed active centers. In this paper, a Mn-doped UiO-66 catalyst was successfully synthesized using a one-step solvothermal method and was applied for the first time to the low-temperature selective catalytic reduction of NO by CO (CO-SCR). The addition of Mn increased the average particle size and specific surface area of UiO-66. Compared with pure UiO-66, the NO conversion rate of Mn<sub>1/6</sub>-UiO-66 in a sulfur-free environment increased from 89% to 98% at 150 °C due to the higher number of active sites and the synergistic catalytic effect of the doped metals. In a sulfur-containing environment, the NO conversion rate at 250 °C remained above 96% in 8 h. |
