摘要：
In this study, it was found that the doping of Co on Mn/TiO2 catalyst could enhance its K resistance. The characterization results showed that the modification of Mn/TiO2 catalyst by Co could increase its reducibility and the adsorption of NH3 and NOx species on it. From the results of in situ DRIFT study, the NH3-SCR reaction over Mn/TiO2 catalyst obeyed the Langmuir-Hinshelwood mechanism. And the addition of K on Mn-Co/TiO2 had little inhibition effect on NOx adsorption. These features made Mn-Co/TiO2 catalyst show better K resistance than Mn/TiO2.
