“…The Mn 2p spectra of five catalysts are presented in Figure b, which are mainly divided into two categories: the peak centers at 654.3 and 643.1 eV can be explained as Mn 4+ , and the peak at 641.7 eV is assigned to Mn 3+ . − As shown in Table , the percentage of Mn 4+ /Mn on Mn/Co-MOF-74 is higher than that of Mn 3+ /Mn. According to the reports, Mn 4+ participates in the reversible oxidation–reduction reaction cycle, which can improve the ability of NO to oxidize to NO 2 , being beneficial for promoting the rapid SCR reaction .…”

To realize the selective catalytic reduction of NO at low–medium temperatures and avoid secondary pollution, a highly active catalyst Mn/Co-MOF-74 was synthesized. X-ray diffraction, X-ray photoelectron spectroscopy, thermogravimetric analysis, Brunauer–Emmett–Teller method, and scanning electron microscopy were employed to analyze the physicochemical properties of catalysts with different Mn/Co molar ratios and conjecture about the difference in the catalytic activity. Meanwhile, the effects of the molar ratio of Mn/Co, catalyst dosage, catalyst synthesis conditions, GHSV, and temperature on the NO conversion efficiencies were investigated and found that an optimal NO conversion efficiency of 93.5% was obtained at 200–225 °C. In the end, the stability of Mn/Co-MOF-74 was investigated and found that the catalyst has better sulfur and water resistance, and the NO conversion mechanism was speculated on the basis of characterizations and literature data.
